" pay a lot of attention to with the acoustics of the room to ensure that we don't get a lot of reflection that it uses.

" But a high and I and now audio equipment part of C yes right the only watch these -- 8000 dollars from the room to pad. -- What I mean yeah obviously you get very soft ceiling you got very soft wall panels in here but they're divided.

" Points to search house speaker that's our most important speaker home theater system because that's what reproduces 80% over here which is dialogue.

I mean ideally we would be directly behind the screen are dealing not block which is what happens in a theater cinema -- But and most home -- replacement is about proposed. To critical thing you want to -- that dialogue onto the picture itself. You're left right speakers are that are reproduce music swells reproduced people moving off stage on the stage for you know race cars -- gunshot is going to hear. Those are about it maybe sort of -- thirty degree angle of the center. In -- surround speakers we basically recommend somewhere between ninety -- 110 degrees and surround speakers."

" Now I notice something you've listed. Do you know degrees of angle for a -- distance so I'm thinking you're basically doing those compared to sort of the senator seated position and."

" Precisely onions and a lot of AV receivers when you set them up they actually askew. You know how how far you from each speaker and then they have set ups menus with in the system soft and it would but balances system. Utilizing white -- a pain point sort of forget it should should should should should promote your speakers when you get nice balanced there. That's a good starting point and then the -- ways you can buy a -- meters reddish active to further to that."

" What seems like as I've actually I've I've done -- you know you. You basically with a with a CD generating noise and basically adjusting the level for each of the speakers around -- system so they're not actually looking like the time it takes you from the speaker's position they are."

" And that's whether that's one of the reasons why they ask you what's the distance from your listening position to that speaker because they they measure. They are looking at time and there's delays this or are built into the AV receiver when your coverage and certain up. Two to basically enable you to get the very best sound from where you."

" So it's probably safe to say that if you receiver has signaled on calibrated so it's probably going to be more accurate that you are sitting in your yours -- with wouldn't be here. But about it engineer that's probably the case since I'm the hormone reports us."

" A -- thank what are the sponsors health osprey and he'll keep you theme music dot com check out system as part of -- you -- dot com. We're doing a couple of fun thing I want every month I created you play a list of songs that sound of music that I enjoy want to share with you. If you go to unity dot com slash system you can actually listen previously the song exactly like. Give me if you like them and they get stuff I'd like you don't let me know about it but there's something even better we've got a deal for you can get it increased don't we say three -- docket no fury and a monthly license no restrictions MP3 format encoded at a high rate downs. -- solid and if the songs for -- do you get a good news.com slash system and sign up today checking out -- us a favor. What our sponsors like music dot com they help create a joke you see."

" Through so much for qwest until we do things now. -- should -- technical marketing manager Billy -- so we're just talking before the camera turned on about. If you if you're building theoretically the perfect room. To put a surround sound system and you're actually looking it measurements so much is preachy news."

" Cracked yet what you want to do innovator as you want to try to avoid hitting her room being its seat twice as what that is -- And you one of what is expecting a ratio that is all. So three to one's badly three point 5321 is exactly why. You just want to avoid sending waves that's pretty attractive so what sustainably. Standing wave is is. The wave that would be basically keep on balancing the same way again and again and we'll just keep on going as it was -- reflecting -- as it is up like when you have sort of a poorly designed Sobel further -- me be a little excessively -- to one particular frequency and you put in the right part of the corner of your room and all of a sudden when you want to you know it's hit the entire room sort of lights up -- it exactly but the ways is through all the way to -- summing up at one point and that. Great for disco not so good for soundtracks. So when your time -- one of the recent developments have been hearing about kind of kind of on the bleeding -- just ran sentence is. These twins -- so what's in the hours spotlight so the first of non directional you have -- all the frequencies below 100 Kurds you know sixty Hertz and I had injured your means speakers are. What's the point of adding in addition also offers. The it is -- to balance here -- a basic you have across the room having won support for solar. That the simple for in general when you set -- theater is probably one of the most people -- it's actually set up the problem is because that the weekends are so long to attend to some. One way or another sometime idiot to cancel also would sometime this summer. It's extremely difficult to find the proper spot for support for so having multiple support for his rule tend to diffuse more debates now. Pick an example when you put your ear so walker and home theater -- deal -- can degrading it is actually to put to support her own account. Exactly where you're sitting -- the -- it'll degrade -- on if you click on accounts and then you walk on the road you're gonna find a point where it actually sounds really good you're gonna have approached greeted night. And once you know what a spot it's your tickets if put it wherever elected. And it's -- exact it is true that the -- if you hear well the base wherever you are when the -- on the couch in duties accepting no way around. Puts the best we can find it. The best enforceable for an -- is that because of of the reflections were talking about -- as you know it's it's something called trust a function. Between the two point so the trust function in the room between the sub and wherever you war is true one way or the other. The justice of funky to -- but no cable that's really the best way -- set -- here's a walker which means that the civil global song go to wherever it is. Doesn't mean it's gonna sound as good if you move its C 34 feet. Right so that when having multiples of -- might be able to kind of covert archer area."

" How how big is kind of the sweet spot on orcas we talk about rating your speakers in and sort of the angle to this sweet spot. But they tend to think of as being the center of the counts but you're you've got a family -- we've all seen the Simpsons where today's laid out in a row on the couch making you can you create a sweet spot that's like seven feet wide."

" So the best with -- create awaits its is to have speakers as far away as possible from the switch. Because I think a bit as well when you have a stereo pair of speakers just stereo. As a during the meal that you which is really the from the image right between. If you start moving on one side and what's gonna get slower than the other and also the the which starts shifting -- so. It when you have -- large distance the percentage of if you look at the length the distance into speakers the amount of movement that you have -- how -- an account for example maybe before I feed that. That this doesn't mean much when the speakers are very far apart. Now if the speakers are really close one another friend and -- small movement will completely change to unity it speakers. So what it waits it quite sweet spot to move the speakers away from the."

" So think about like by my sort of living room from hell which is all collapsed -- last year Ericsson fireplace here and it's really long this way if I wanted to -- sweet spot would work better it is sort of you know -- the couch in front of the main entrance and -- got some more distance from the speakers sensitive but Leo it could -- aesthetic way to do it perfect view it -- an -- to remove account further. Criminal there it is these spousal acceptance factor these very low enough to goes to a what is dubbed the dining room table honey we'll put it. There area that's thats gonna go over well so when the things we haven't really addressed is. It seems like talking about sort of the angles that are involved and the positioning it involves a lot of people kind of don't rock bed. Music basically traditional stereo speaker position is a little bit different media lot different racing -- up from surround sound speakers. Can be -- pretty good but I notice like it and I've got some some serious un your nerd friends and at the real high and out of control like IP too much money for my provide copper cable and a -- It almost seems like a lot of them have a set of stereo speakers for listening to music and and have their their home theater system. Yes it's just ridiculous sir."

" Though right you know you're an engineer you can -- the executive going so well some days or. Whether stereo or multi channel it's all about being emotionally get out of it whether you speakers are widely case but that's what -- like that really white image or a very narrow because of something highly directional -- have -- watch -- It's matter of a three days I don't think there's anything wrong with having to. Dodged eggs and we -- amounts of the ratios are -- like them you know who seems like there's this particular. It seems like the angle you use for it stereo setup will be different and and those humans for a surround sound system there is just there for several somebody's who is since you do is called the I use standard and yet you standard is so if you mentioned senator of being zero degree map of each hour and a thirty degree. Plus and minus thirty you're gonna have the -- right channel. And then a 105 degrees and let her own rights and that's the standard right totality of it being makes now if you have a hundred or ninety or 120."

" Okay inspected the classic you know what sounds good you just roll with it has yet I've heard some high and that 50000 dollars speakers -- Repair clips is that a twelve your -- about a garage sale of sound better but I do what you gotta do affect the habit what's the what's the biggest challenging for for in terms of of what you will be looking for in terms of the receiver. And so surround sound speakers you price probably can't get brand specific. Unit -- loves although -- equally yet goods is that a bad thing to say it. -- the service with an audio industry you've gotta keep sensible boom which people be looking for the walk in there they're they're looking for receiver looking for speakers where you guys -- human story."

" Definitely I would say these days you have to -- him. Now it's it's a critical aspect of home theater these days. It's been difficult in the past two all these cables went into the back of the if you are going to fatigue are -- in my it is is a good way to go. It also carries digital audio so you tend to preserve the consequence it better. Obvious that as well placed in my definitely is one element."

" HDMI is that finally gonna be able to carry. True HD signals over HDMI were those -- actually -- what is currently there -- some issues especially with some of the early Blu-ray players yeah in fact there were some wailing and -- and -- clothing as people come culminating you can true HD experience it with you know might -- giant silver and you -- back. You know -- I gotta say like five point one cents brigades -- one okay -- bit more. What's the point of going to -- on compressed form. -- is -- is it is it -- as you wrongly called to reach the united compressed form."

" So it it is. Lossless meaning that what you hear is exactly what has been -- studio so it is compressed it's compressed mathematically so it is culinary expert -- decoder. And then at the decoder is physically a code that is. Just like Wednesday for example represents labels just the president probably never loses anything."

" All the data's there they just make it regardless it just try to -- Do you find mean you know is that is -- most people actually hearing the additional his you know never occurred to me like you know -- when he killed it MP3 I know what's -- you know no matter what anybody says it's not. You know it's not an audio C I can't hear the difference especially in certain types of instruments and stuff. Are there a lot of people I mean there are people can actually hear the difference between a compressed five while want to seven point one. So today she's what you get so caught by one at some point one but if I sort trying to do all the dolby acronyms that'll stop my."

" That when he comes to compress audio it's it's -- deal evolved. So sort of training or experience with -- I mean when -- if you three came around I liked that 128 -- it was just have been iPhone. I want to need to be awesome and in this overtime but I've picked up on one thing and -- and opening it. As soon as he noticed them there's nothing could gamers -- around here and now we're only gonna notice all of them so it's all about picking up these things over time. That. Think of it when it comes to true Christine what people like the most -- trustees is that. They're saying I don't know African here. These differences are no but I just want to make sure that I won't hear anything wrong so just to be a perfect. What you do something wrong because I'm mildly you know here it. So a lot of support she ultra she's just because it is perfect and the ability want."

" This is perfect these are gonna get from the studios yes exactly without actually getting a full Princeton and there. Of rather high end system in -- exactly."

" Our sponsors help bring the show do you take a moment did listen this message for one of the sponsors of today's episode system dolby. -- anybody and everybody talks and HDTVs and -- is more than half of the digital entertainment expo here it's and is an integral part of digital entertainment today dolby and its technology -- power the world's most popular integrated entertainment products from the giant cinema plex theater. To your -- chances are sometime in the near future and health and here you. Adobe continues the enemy lead audio and they've expanded their portfolio to include new video technologies to address the quote total entertainment experience -- With 3-D digital cinema hiding -- screens video and on the go for mobile and portables look don't think. Cutting it since I was playing around on my dad's reel to reel decks in the seventies and they are still cutting its today powering them best audio technology inside of Blu-ray dvd. Do yourself a favor when you're shopping for your home theater experience -- your casualties included new digital reads the entertainment products --"

" So what we look forward to next is there going to be nine point wanted to going to be additional surround sound speakers and Ed of somewhere in this building and no one point there was like a you know 32 dot seven or something crazy like that where you literally sitting in -- dinner -- you know there there were literally speakers and about 270 compass points it's like."

" Credit it's if it's there it's called a sandbox that is that what we call it and we just going to experiment with -- It is difficult because. We when you start thinking about more than five point 17 coolant the benefit of -- of what was to. The benefit of the gap between this -- right or wrong when you try to patent something with -- literally throw it. It's better to have its -- depending across. If you start to go beyond them. You know it gets more and more complicated more and more cables. There are some benefits. You know some people are expected with -- channels will be what experiment with that -- right boys the people. That idea. The former is that yes -- she was using center left center right stimulus so. People have expressed -- with all the stuff and what's interesting is is today into -- standard these speakers location have been defined so it is part of the blue expects to have. I speakers with white speakers to have something etc. always look great speakers now. It's really gonna come down to the cult it now if that's it studios thing that part is going to be great. Then it's gonna happen if picking guys thing that I that would go it's gonna happen it really depends on the content. We have experimented witted and we think -- there is some benefit quit for terrible fight what is the greatest benefit of all right after that it's just. You almost exactly but you have some just -- human to -- is that sort of surround sound speakers at different levels or how to network so. No in general when you talk about heightened hear me talking about the from both at a time and -- If you look at the center expects this because that I've been officially defined by computer industry are. You have -- which is credible let tunnel and yes and hide right -- and it pops around which is single speaker write a book you. So that's what has been defined. Now we ultimate helicopter sort of task exactly yes something -- over here there so these -- the height channels the we'd been defined."

" That would be 123456. In the front and then another three in the back plus one -- so six. It's nine -- the hard 6410. Of the eleven B eleven speakers plus the symbol for habitable perhaps nothing else to go. But hey that's. Yeah I mean it's in the fine I don't who knows maybe studio -- it is will use it -- it we don't know yet but. It's the potential workers if if you're thinking in terms of -- actually when when -- playing on yours yours -- have speakers -- awards and what one. Height doesn't seem to make much difference in the rear speakers yes that's what about the prospects -- he would feel so them."

" When you look at the -- acoustics of do we we perceive zone one thing it is really interesting is. The accuracy that the brain in perceiving movement's -- anything that you can actually see. So if you haven't it's a little bird you know -- French and that burdened -- by one degree you can actually feel that movement. Now if you have the exact seems so behind you the songs to move but fifteen to twenty degrees before actually being perceived as having little. So when it comes to high channel in the back it's probably not the best place would agree that what you really want to do this -- Frogs first and then you want to start -- the backwards because we're we're more to do threats or changes in our farm yeah over over our lifetime we physically -- to you know here is solid look at it and find it -- that means executives and with its -- it's expected."

" So what's that when you're -- would would we talk about Psycho who's who's really hasn't heard that phrase before and it's kind of like busily doodling what's the what's the would you would you -- Psycho acoustics. A lot of things. So you're lighting up you say this is obviously I don't --"

" At the -- circus sticks isn't Kabila is actually a lot of things it could be that we perceive some to say do the way you. Nowhere -- coming from for example so very simple principle is when you have a phone on your right on your but it left. The song is gonna reach and it here first and then the right here. So the brain has his immunity to measure the time delay between the two years so it will know that it's here. Now the problem is just time it is not enough because here and there have exact thing today. So then you start having the frequency response of the two cells so the way did it user -- there should be completely symmetric. And any any sound and moves around we will have a very specific equalization. To your here. Which means that a song that is coming from. Behind you or follow your wallet -- arrives at you know the -- that both hear the same time we'll have different frequency response behind or concern for. So the brain learns oldies -- physically overtime minutes of when you can start picking up things that we go where they are. The other aspect of such acoustic is what you can hear what you cannot hear and that's what made it an -- The digital you know MP3 you know these formats where the goal is. What is it that you cannot hear what today that can get rid of orbital pressing further so technical sticks his physically he's. To mean things those."

" We've talked about sort of how he locates speakers in the room behind the speakers how to tune in the room what can we haven't talked that is sort of different speakers you know we talk about you've got sort of a little you know. Cubes it's basically one little sort of you know it's an oversized Tweeter undersized sort of mid -- speaker written like full size speakers like these paradigms have set up here as are any major difference in your laying out sort of a set of smaller versus larger speakers sir."

" I think it's all about lifestyle and it's what can you tolerate. If you're. Where he -- it really currently sentence factor can be -- exactly and it overall it went. I guess we should never forget that it's against Sony's very emotional and so people would be absolutely fine with having to be useful Cuba and civil critical deal at all the meat in Orange. Some people might like having to sell extremely accurate and also of the within want to beat Rommel. So it's all about preferences I would say. Small home -- to books or can be actually you know performing really well very high end systems are obviously. Not everybody local satellite speakers systems are equal I -- not yet decided you most that are pretty nice wherever you know what basically amounts of fringe boring speaker but. He put that against the full range for what type or standards -- here in deference to authority that I think the most critical aspect about it was Apple Computer is -- have to -- matched speakers. It it's extremely. Knowing when you have the bush you know intentionally goes to the right moment it's a different that the speaker of soda the temperature changes and any goes to the song is complete different again. So if you can match -- could have. Five channels are identical or hosting -- it's."

" It -- The speed goals of the speaker designers if and -- community comes back taxes crimes and -- layers so 80% your sound is really coming through that center channel. Running at channel. Now if it thank you so much good to welcome us."

" Through so much for qwest until we do things now. -- should -- technical marketing manager Billy -- so we're just talking before the camera turned on about. If you if you're building theoretically the perfect room. To put a surround sound system and you're actually looking it measurements so much is preachy news."

" Cracked yet what you want to do innovator as you want to try to avoid hitting her room being its seat twice as what that is -- And you one of what is expecting a ratio that is all. So three to one's badly three point 5321 is exactly why. You just want to avoid sending waves that's pretty attractive so what sustainably. Standing wave is is. The wave that would be basically keep on balancing the same way again and again and we'll just keep on going as it was -- reflecting -- as it is up like when you have sort of a poorly designed Sobel further -- me be a little excessively -- to one particular frequency and you put in the right part of the corner of your room and all of a sudden when you want to you know it's hit the entire room sort of lights up -- it exactly but the ways is through all the way to -- summing up at one point and that. Great for disco not so good for soundtracks. So when your time -- one of the recent developments have been hearing about kind of kind of on the bleeding -- just ran sentence is. These twins -- so what's in the hours spotlight so the first of non directional you have -- all the frequencies below 100 Kurds you know sixty Hertz and I had injured your means speakers are. What's the point of adding in addition also offers. The it is -- to balance here -- a basic you have across the room having won support for solar. That the simple for in general when you set -- theater is probably one of the most people -- it's actually set up the problem is because that the weekends are so long to attend to some. One way or another sometime idiot to cancel also would sometime this summer. It's extremely difficult to find the proper spot for support for so having multiple support for his rule tend to diffuse more debates now. Pick an example when you put your ear so walker and home theater -- deal -- can degrading it is actually to put to support her own account. Exactly where you're sitting -- the -- it'll degrade -- on if you click on accounts and then you walk on the road you're gonna find a point where it actually sounds really good you're gonna have approached greeted night. And once you know what a spot it's your tickets if put it wherever elected. And it's -- exact it is true that the -- if you hear well the base wherever you are when the -- on the couch in duties accepting no way around. Puts the best we can find it. The best enforceable for an -- is that because of of the reflections were talking about -- as you know it's it's something called trust a function. Between the two point so the trust function in the room between the sub and wherever you war is true one way or the other. The justice of funky to -- but no cable that's really the best way -- set -- here's a walker which means that the civil global song go to wherever it is. Doesn't mean it's gonna sound as good if you move its C 34 feet. Right so that when having multiples of -- might be able to kind of covert archer area."

" How how big is kind of the sweet spot on orcas we talk about rating your speakers in and sort of the angle to this sweet spot. But they tend to think of as being the center of the counts but you're you've got a family -- we've all seen the Simpsons where today's laid out in a row on the couch making you can you create a sweet spot that's like seven feet wide."

" So the best with -- create awaits its is to have speakers as far away as possible from the switch. Because I think a bit as well when you have a stereo pair of speakers just stereo. As a during the meal that you which is really the from the image right between. If you start moving on one side and what's gonna get slower than the other and also the the which starts shifting -- so. It when you have -- large distance the percentage of if you look at the length the distance into speakers the amount of movement that you have -- how -- an account for example maybe before I feed that. That this doesn't mean much when the speakers are very far apart. Now if the speakers are really close one another friend and -- small movement will completely change to unity it speakers. So what it waits it quite sweet spot to move the speakers away from the."

" So think about like by my sort of living room from hell which is all collapsed -- last year Ericsson fireplace here and it's really long this way if I wanted to -- sweet spot would work better it is sort of you know -- the couch in front of the main entrance and -- got some more distance from the speakers sensitive but Leo it could -- aesthetic way to do it perfect view it -- an -- to remove account further. Criminal there it is these spousal acceptance factor these very low enough to goes to a what is dubbed the dining room table honey we'll put it. There area that's thats gonna go over well so when the things we haven't really addressed is. It seems like talking about sort of the angles that are involved and the positioning it involves a lot of people kind of don't rock bed. Music basically traditional stereo speaker position is a little bit different media lot different racing -- up from surround sound speakers. Can be -- pretty good but I notice like it and I've got some some serious un your nerd friends and at the real high and out of control like IP too much money for my provide copper cable and a -- It almost seems like a lot of them have a set of stereo speakers for listening to music and and have their their home theater system. Yes it's just ridiculous sir."

" Though right you know you're an engineer you can -- the executive going so well some days or. Whether stereo or multi channel it's all about being emotionally get out of it whether you speakers are widely case but that's what -- like that really white image or a very narrow because of something highly directional -- have -- watch -- It's matter of a three days I don't think there's anything wrong with having to. Dodged eggs and we -- amounts of the ratios are -- like them you know who seems like there's this particular. It seems like the angle you use for it stereo setup will be different and and those humans for a surround sound system there is just there for several somebody's who is since you do is called the I use standard and yet you standard is so if you mentioned senator of being zero degree map of each hour and a thirty degree. Plus and minus thirty you're gonna have the -- right channel. And then a 105 degrees and let her own rights and that's the standard right totality of it being makes now if you have a hundred or ninety or 120."

" Okay inspected the classic you know what sounds good you just roll with it has yet I've heard some high and that 50000 dollars speakers -- Repair clips is that a twelve your -- about a garage sale of sound better but I do what you gotta do affect the habit what's the what's the biggest challenging for for in terms of of what you will be looking for in terms of the receiver. And so surround sound speakers you price probably can't get brand specific. Unit -- loves although -- equally yet goods is that a bad thing to say it. -- the service with an audio industry you've gotta keep sensible boom which people be looking for the walk in there they're they're looking for receiver looking for speakers where you guys -- human story."

" Definitely I would say these days you have to -- him. Now it's it's a critical aspect of home theater these days. It's been difficult in the past two all these cables went into the back of the if you are going to fatigue are -- in my it is is a good way to go. It also carries digital audio so you tend to preserve the consequence it better. Obvious that as well placed in my definitely is one element."

" HDMI is that finally gonna be able to carry. True HD signals over HDMI were those -- actually -- what is currently there -- some issues especially with some of the early Blu-ray players yeah in fact there were some wailing and -- and -- clothing as people come culminating you can true HD experience it with you know might -- giant silver and you -- back. You know -- I gotta say like five point one cents brigades -- one okay -- bit more. What's the point of going to -- on compressed form. -- is -- is it is it -- as you wrongly called to reach the united compressed form."

" So it it is. Lossless meaning that what you hear is exactly what has been -- studio so it is compressed it's compressed mathematically so it is culinary expert -- decoder. And then at the decoder is physically a code that is. Just like Wednesday for example represents labels just the president probably never loses anything."

" All the data's there they just make it regardless it just try to -- Do you find mean you know is that is -- most people actually hearing the additional his you know never occurred to me like you know -- when he killed it MP3 I know what's -- you know no matter what anybody says it's not. You know it's not an audio C I can't hear the difference especially in certain types of instruments and stuff. Are there a lot of people I mean there are people can actually hear the difference between a compressed five while want to seven point one. So today she's what you get so caught by one at some point one but if I sort trying to do all the dolby acronyms that'll stop my."

" That when he comes to compress audio it's it's -- deal evolved. So sort of training or experience with -- I mean when -- if you three came around I liked that 128 -- it was just have been iPhone. I want to need to be awesome and in this overtime but I've picked up on one thing and -- and opening it. As soon as he noticed them there's nothing could gamers -- around here and now we're only gonna notice all of them so it's all about picking up these things over time. That. Think of it when it comes to true Christine what people like the most -- trustees is that. They're saying I don't know African here. These differences are no but I just want to make sure that I won't hear anything wrong so just to be a perfect. What you do something wrong because I'm mildly you know here it. So a lot of support she ultra she's just because it is perfect and the ability want."

" This is perfect these are gonna get from the studios yes exactly without actually getting a full Princeton and there. Of rather high end system in -- exactly."

" Our sponsors help bring the show do you take a moment did listen this message for one of the sponsors of today's episode system dolby. -- anybody and everybody talks and HDTVs and -- is more than half of the digital entertainment expo here it's and is an integral part of digital entertainment today dolby and its technology -- power the world's most popular integrated entertainment products from the giant cinema plex theater.

Do yourself a favor when you're shopping for your home theater experience -- your casualties included new digital reads the entertainment products --"

" So what we look forward to next is there going to be nine point wanted to going to be additional surround sound speakers and Ed of somewhere in this building and no one point there was like a you know 32 dot seven or something crazy like that where you literally sitting in -- dinner -- you know there there were literally speakers and about 270 compass points it's like."

" Credit it's if it's there it's called a sandbox that is that what we call it and we just going to experiment with -- It is difficult because. We when you start thinking about more than five point 17 coolant the benefit of -- of what was to. The benefit of the gap between this -- right or wrong when you try to patent something with -- literally throw it. It's better to have its -- depending across. If you start to go beyond them. You know it gets more and more complicated more and more cables. There are some benefits. You know some people are expected with -- channels will be what experiment with that -- right boys the people. That idea. The former is that yes -- she was using center left center right stimulus so. People have expressed -- with all the stuff and what's interesting is is today into -- standard these speakers location have been defined so it is part of the blue expects to have. I speakers with white speakers to have something etc. always look great speakers now. It's really gonna come down to the cult it now if that's it studios thing that part is going to be great. Then it's gonna happen if picking guys thing that I that would go it's gonna happen it really depends on the content. We have experimented witted and we think -- there is some benefit quit for terrible fight what is the greatest benefit of all right after that it's just. You almost exactly but you have some just -- human to -- is that sort of surround sound speakers at different levels or how to network so. No in general when you talk about heightened hear me talking about the from both at a time and -- If you look at the center expects this because that I've been officially defined by computer industry are. You have -- which is credible let tunnel and yes and hide right -- and it pops around which is single speaker write a book you. So that's what has been defined. Now we ultimate helicopter sort of task exactly yes something -- over here there so these -- the height channels the we'd been defined."

" That would be 123456. In the front and then another three in the back plus one -- so six. It's nine -- the hard 6410. Of the eleven B eleven speakers plus the symbol for habitable perhaps nothing else to go. But hey that's. Yeah I mean it's in the fine I don't who knows maybe studio -- it is will use it -- it we don't know yet but. It's the potential workers if if you're thinking in terms of -- actually when when -- playing on yours yours -- have speakers -- awards and what one. Height doesn't seem to make much difference in the rear speakers yes that's what about the prospects -- he would feel so them."

" When you look at the -- acoustics of do we we perceive zone one thing it is really interesting is. The accuracy that the brain in perceiving movement's -- anything that you can actually see. So if you haven't it's a little bird you know -- French and that burdened -- by one degree you can actually feel that movement. Now if you have the exact seems so behind you the songs to move but fifteen to twenty degrees before actually being perceived as having little. So when it comes to high channel in the back it's probably not the best place would agree that what you really want to do this -- Frogs first and then you want to start -- the backwards because we're we're more to do threats or changes in our farm yeah over over our lifetime we physically -- to you know here is solid look at it and find it -- that means executives and with its -- it's expected."

" So what's that when you're -- would would we talk about Psycho who's who's really hasn't heard that phrase before and it's kind of like busily doodling what's the what's the would you would you -- Psycho acoustics. A lot of things. So you're lighting up you say this is obviously I don't --"

" At the -- circus sticks isn't Kabila is actually a lot of things it could be that we perceive some to say do the way you. Nowhere -- coming from for example so very simple principle is when you have a phone on your right on your but it left. The song is gonna reach and it here first and then the right here. So the brain has his immunity to measure the time delay between the two years so it will know that it's here. Now the problem is just time it is not enough because here and there have exact thing today. So then you start having the frequency response of the two cells so the way did it user -- there should be completely symmetric. And any any sound and moves around we will have a very specific equalization. To your here. Which means that a song that is coming from. Behind you or follow your wallet -- arrives at you know the -- that both hear the same time we'll have different frequency response behind or concern for. So the brain learns oldies -- physically overtime minutes of when you can start picking up things that we go where they are. The other aspect of such acoustic is what you can hear what you cannot hear and that's what made it an -- The digital you know MP3 you know these formats where the goal is. What is it that you cannot hear what today that can get rid of orbital pressing further so technical sticks his physically he's. To mean things those."

" We've talked about sort of how he locates speakers in the room behind the speakers how to tune in the room what can we haven't talked that is sort of different speakers you know we talk about you've got sort of a little you know. Cubes it's basically one little sort of you know it's an oversized Tweeter undersized sort of mid -- speaker written like full size speakers like these paradigms have set up here as are any major difference in your laying out sort of a set of smaller versus larger speakers sir."

" I think it's all about lifestyle and it's what can you tolerate. If you're. Where he -- it really currently sentence factor can be -- exactly and it overall it went. I guess we should never forget that it's against Sony's very emotional and so people would be absolutely fine with having to be useful Cuba and civil critical deal at all the meat in Orange. Some people might like having to sell extremely accurate and also of the within want to beat Rommel. So it's all about preferences I would say. Small home -- to books or can be actually you know performing really well very high end systems are obviously. Not everybody local satellite speakers systems are equal I -- not yet decided you most that are pretty nice wherever you know what basically amounts of fringe boring speaker but. He put that against the full range for what type or standards -- here in deference to authority that I think the most critical aspect about it was Apple Computer is -- have to -- matched speakers. It it's extremely. Knowing when you have the bush you know intentionally goes to the right moment it's a different that the speaker of soda the temperature changes and any goes to the song is complete different again. So if you can match -- could have. Five channels are identical or hosting -- it's."

" It -- The speed goals of the speaker designers if and -- community comes back taxes crimes and -- layers so 80% your sound is really coming through that center channel. Running at channel. Now if it thank you so much good to welcome us."
