After watching this video I realized I need a new house, not new speakers :(((
🤣🤣🤣🤣🤣🤣🤣🤣🤣
Ikr
As funny as your reply is, it is dead on. I understand what he is saying in theory but, as you already know, room size and many other factors, make that either extremely difficult or impossible.
BTW, you owe me a drink for the one I spit out after reading your reply😁😁😁
Tell me about it!
😅 haha, me too 🤭
Such an arrangement would be wonderful if I owned a mansion, but since I live in a small frame house, I make do with setting my 7.1 speakers where I can. They work well enough for me too.
Just cam on to this cux I'm try to set up system...who in the hell had 1 couch in the middle of a room...no 1 I know...lmfao
@@TheMotscham Not even theaters have that distribution haha
This is all well and good as long as your lounge is the size of a football pitch.
Yeah, how many rooms can actually manage this kind of setup? Dedicated home theatre rooms maybe, but in most rooms not a chance
Nice video, but impractical. Most people I have seen do not have the option to set the speakers up in a circle in this manner. This is where tuning the receiver for the distances comes in hand. So while this video gives a nice basic explanation of positioning, more than likely, if someone is spending money for surround, they are going to have a receiver that will compensate for speakers being at odd distances in a rectangular room, and in most cases, the receivers come with a special mic to put at the center of the listening area, and it will auto tune the speakers for you. Just think about an actual movie theater. It isn't a circle.
If you use that microphone that measure this distances that sometimes follow with the AV-receiver. I've seen NONE using this, and the surround is all madness. In most cases it is not even used as surround, but it is still in stereo with some surround-FX applied. LOL 😂
Edit: The problem with these uneven mic-measurements is that you will get into odd phase-shifts and weird sounds (filter characteristics).
Just measure to a specific point where you’re sitting from each speaker. Then said that distance in your receiver. Problem solved.
@@Foreverjazzfan Absolutely not. Have you heard how that EQs the sound. It is utter garbage doing such adjustments. Just move yourself instead.
@@rabarebra Moving yourelf is unlikely to be practical, if you have a decent sized screen, you will be atleast 10-12ft away from the screen, so to put your rear speakers equi distnance away would require a 20x20ft room (and, acoustically, a sqaure room is a bad idea). A system shouldnt ruin the sound simply by delaying the channel a few ms, I am setting my home cinema up now, but my Blu-ray has indvidual speaker delay on, and whilst I have only been using stereo til now, I have delayed the sound to get lip sync. If your receiver is ruining the sound, maybe you need to upgrade?
Agreed. Few people have a large enough room to allow equal spacing. Most rooms do not permit enough space for the surround speakers (rear and/or sides). This is where adjustments are needed via the AVR. I wish I could have a dedicated media room to setup the perfect environment and sit in the center.
There is very little professional level YT content dedicated to non-optimal room designs and are almost always geared towards people with the dedicated/perfect room (again, allowing center seating).
In a 5.1 setup the surround speakers go to your sides facing the listening position. When you move up to a 7.1 THEN you add the rear speakers, not the other way around as this video suggests.
And all your speakers don't NEED to be equal distances. Any good receiver is going to have room correction software that will measure and account for the distance of your speakers.
Agree
Cinema Sound, you mention not to put speakers on the ceiling. What about Dolby Atmos which requires that?
This is the longest conversation I've ever heard people have in Chinese 😁
room correction is a feature in the better "home theatre" systems. no pro system relies on that. if you have a good amp, you build your house around it. unless you cant pay for that, you shouldnt listen to music or watch movies on a good system. you are just not worth it
the only issue with delay is lip sync. for each foot of difference between the farthest speaker and the closest speaker there will be a 1 millisecond additional delay. the furthest speaker will fire first and then the closest speaker will fire a few milliseconds after so you hear them at the same time particularly if your rears far far away you will have lip sync issues between the front speakers and screen. your average screen has a video feed response time of 5 ms so nowadays(not input lag), it is a good idea to not have a difference speaker distance per foot more than the response time or so. I have always preferred to have my "surround" channels(which I prefer to call rears usually) about 120 degrees with 5.1. If adding "rear" for 7.1 I'd bring the surrounds to 90° and raise them up so a bit so tweeters hit all listeners and delays are more even. The correct distance between fronts to sides to rears is important, 80° like the video shows is no good better to have them at 110 so tweeters hit each listener and have rears straight behind pointing towards the center channel.
Very well explained sir! Learned so much from watching less than 5 min video on spkr placements. Thank you!
In a perfect world this would be great but viewing areas often arent so cut and dry to enable this set up. For example if your normal viewing position is right up against a wall your gonna have 1 speaker way closer to you than the other. That's when you have to tweak out pot on these speakers and it becomes far more difficult.
Can't believe it but I have my speakers just like you said. Thanks
I know this is an older video, but even processors back when this video was made account for distance and time delay so you don't need everything to be perfectly symmetrical. Your subs go where they have the best bass response. Your processor will take care of distances and delay. Of course this is assuming your run something like Dirac or Audyssey.
Guess you never heard of digital delay and level control have you?
Can’t you just calibrate your receiver to account for a different speaker placement
Of course. But how would you do that if you didn't have a receiver that had a built in calibration protocol and microphone?
Cinema_Sound You can manually do it by measuring your distance from each of the speakers and then putting it on the receiver, and I’m pretty sure that 90% of the people watching this today will have receivers that can do either of these features And if not go on eBay and spend 50 bucks to get a new receiver that can do this
A big wow...Very informative video. I was captivated by the speaker. Thank you for sharing with us such a great audio information.
Its very informative about Sound Positions for Speakers.Done well great job lets have a watch again this video.
Superb video. Many thanks 😊
With a room full of furniture and a room that isn't perfectly round or square, this just isn't realistically possible. I put my speakers where I can lol
it depends on how serious you take this hobby. I worked around this problem by slowly buying my furniture around the speaker system rather than vice versa. It still doesn't look too much like a home theatre and still like a living room but it's almost as the video suggests.
Great information. Thanks!
4:16 I thought that was my baby haha
What do you do if your listening position is back against the wall? Where do you put the back surround speakers?
Excelente proyecto, los felicito sigan adelante, Saludos desde Venezuela.
nice video, straight to the point, and visual explanation
My surrounds left and right are on the back wall but way further than the surround back and up with down facing angle. And properly angled, the back ones are just facing down more and it works!!!!
What about the height of the surround speakers? Should they be at the ear level? Thank you!
No absolutely not they should be about 3 feet above your ear...
Whats up with the non-stop flashing advertisement/vendors?
Absolutely Brilliant..Changed my entire experience..💯💣👍
I just watched this video. Very well explained.
Question:
If one can’t get the the surround distance you suggest, does the electronic distance and levels adjustments in the AVR compensate for this? Thanks
it does
very nice video! quick question what if you have a rectangular room,?should you bring the speakers closer (farther from tv) to make that perfect circle or should I just adjust the speaker levels on the receiver? also if i use height speakers, should they be directly above me or should they be in front/ behind me?
great video, i learned something new, the golden triangle! maybe do something about the dipole speakers placement and the controversy between object based audio vs dipole speakers? that should help people making the right decision when buying equipment in the future. and maybe something about hires audio & speakers? too much people neglect these details, that information is gold.
I dont know anyone that has a room like this. Yes in a demonstration room were your trying to sell speakers maybe you'd be in a room like that but most people don't but with that said nice video...
Good video, but doesn't room correction adjust for distance\delay and levels? Like Audyssey.
Just let the receiver calibrate the listening spot and then adjust with your ear to get it just right, most homes won't work "the perfect speaker position".
@@cinema_sound5003 My friend.. Audio signals delaying is one of most common techniques in proffesional audio engineering, thats your opinion can be fairly described as urban legends of Hi-Fi maniacs..
If only i had a cinema room this would be fine
When setting up a receiver with the included mic, does it typically calibrate volume, synch, or both?
I can appreciate the logic here, especially with pulling the FR-L & FR-R speakers forward to line up with the center channel... which I'll do tonight!
However, in virtually every video I've seen thus far on this subject, there exists this fantasy world where all this extra space exists behind the listening position. Not for me.
I'm like many others, who have a tiny place. My couch is right up against the damn wall. No luxury of said large room, but I still want my 7.2.2.
My surround L&R Surround are to my 9:00 & 3:00, on their own speaker stands for now, just to build the soundstage.
My Surround Backs or Atmos' (or whatever we call them) are at ear level atop the far back corners of the couch, because I haven't quite decided where they should actually be (I'm using old Bose 2001s from a galaxy far far away... drivers facing me, tweeters facing ceiling... I figured they're Direct/Reflecting design would be ideal as Atmos surrounds.)
I used the Audessey mic setup on my Marantz NR1711, & thus far it sounds pretty bad ass. But if I'm going to change the Surround Backs to Atmos Heights, what's the best location, when I'm in a small square space with very little area behind the listening position? Is it even worth changing at this point? If my environment is small, is moving those 2 going to create that big a difference? Feeling a bit to lazy to run more wiring & find an elevated mounting solution, but might try it in the future...
The only way to have a center speaker sound coming directly from the screen is to have an 8k screen that only has 4k of pixels with a checkerboard of holes missing so sound can come out of it. You could have voice sounds coming directly from the mouths :)
Funny 😂
@@rabarebra Sony already invented it now it's called Acoustic Surface Audio+. The sound comes from the mouths by vibrating the screen.
@@warlockboyburns "Vibrating the screen" 😂
@@rabarebra Yes that's the technical term
@@warlockboyburns Good luck, would never buy anything like that. Wouldn't compete with any fidelity I am used to.
thank you very much
what a nice Speakers video it is!! Greetings from my heart
After watching this video i realized i need a new life, in which i could afford these things!
A good HT receiver's setup can compensate for different distances.
what if your main wall is not straight it is angled so front right left center good and the couch is center where to put the rears at a angle ? or just behind the couch.
Uptading from normal two speakers to 7. 1
(This video helped me so much)
I have a open floor in my condo so do i do this with home theater.
...or use the AV receiver to time correct phase for unequal distanced speakers
Went with Bi-polar rears and eliminated all the geometry needs. More expansive sound. Def Tech SR9040s are awesome. Just ensure your auto calibration on your receiver ignores these during setup as they confuse the AV unit.The included guide walks you through proper settings.
My mother and stepfather put all of the speakers in the front. I'm not allowed to touch the speakers.
Wow! thank you for this very informative video!
What the correct position for ceiling speakers.
How do you set up distance. 0 to 3 m? Which do I choose?
My problem Is my room no 4th wall, can't move listening position into the center of the room, only place for listening against back wall along with surround speakers
And Why don't we use floor standing speakers for are surround sound?
Excellent video and very good
Very very nice video i like it.
Where are the links you mentioned ? (Dolby site and that set ip program, groop or ?)
searched and searched for a video explaining the best way to mount my sonos system speaker for 5.1 and you guys did a great job explaining it. One question if I understand this correctly its better to the the speakers close to ear level for height vs up in the air in the corner of the room aimed down? My problem is with my open floor plan I have no outlets directly behind my couch so I can only mount them along the walls in the room.
Ok. Thanks. I think I will experiment with different heights and see how they sound before buying any kind of mounting bracket.
Thanks Mark, that helps a lot!

Ain't no body house furniture is set up like what you show to support a home theater. I understand it's the proper positioning to get the most outa you're surround sound but to some people(ME) it's sort of discouraging to even get a surround sound jus cause my living area could never be set up like this.
This is absolutely true. The optimal placement is really just something to aspire to. Basically, try your best to get as close to it as possible. However, unless you have a dedicated home theater room, you basically have to "make do" with what you have. That may mean one surround speaker much further away than the other, or the surrounds not quite optimally placed. The good thing is our hearing is not so accurate, and the placement in the surrounds is not so precise that things will be thrown off too much by having the speakers slightly out of alignment. Room correction in your AV receiver can generally fix any difference in speaker distance--it may not be 100%, but it will be good enough. The end result may not be "ideal", but it will be close enough to get the job done. For the most part unless you do a really horrendous job of placing the speakers or have an absolutely terrible room to work with, you'll end up with a decent outcome.
Just do the best you can. It will be good.
Our basement is sort of set up like this, with a 5.1 surround home theater setup, except that we have the side speakers on the ceiling.
The best thing is keeping speakers away from the floor and placing them above ear level
Thank you for this information you are really a good person
My room is 13' x10'........i have the tv on a 13ft wall side....the room is a rectangle....i cant figure out a good position for my 5.1 system...i know the basics...but sometimes the basics dont apply
The subwoofer crawl is the best way to determine the best placement for compact bass.
we've got a U shaped couch with the right side against the wall. so i guess its impossible to have good audio for everyone. unless i would mount everything on the ceiling, but wouldnt that sound weird tho?
Hi,
I am planning to get 85" QLED(2021 Q70A) and a matching sound bar to have home theatre setup in my lounge space.
My lounge size is 12.5 foot depth, width is 10.5 foot and ceiling height is 7.9 foot. I wish to have 4 seats in a row. Mostly i watch regular TV shows, movies, and sports. I dont play games on this home theatre.
Could you please advise on choosing between Home theatre soundbar samsung HW-Q900A and Q870A(2021). Both are in same price the range.
HW-Q900A has 7.1.2 channel sound without rear speakers.
HW-Q870A has 5.1.4 channel sound with wireless rear speakers.
Could you please suggest me to choose the better soundbar from the above two and few tips on setup, considering my room space, TV size and seating capacity.
Thanks in advance.
In a 5.1 and a 7.1 its not a magic triangle its a magic X meaning fronts are in line with the rears your center goes though the center of the x and your left and right surrounds go though the middle of that same x and your listening area is in the middle and make sure you turn your fronts and rears 30 degrees out from the wall do not make them flush with the wall this set up works well with movies music and if you have it hookup games as well.
Hope this is a better understanding, this is the exact setup i use for years just make sure your fronts and rears towers are off the floor bass hates carpet with powered subs this doest apply at all but find a good location for you sub or subs
This works with any size room in a house appartments your going to have to adjust to your environment
Not all room are equal but its a start again hope this helps
Amazing video. Thanks for sharing!
Very useful video, make it more! Congratz!
amazing tutorial, must try
Thanks for the video. I have my speakers set up in this way. The question I have is, I have 2 rear speakers left & right, but when I play music the rear speakers seldom go off. What affects the rear speakers being triggered?
It would be whatever your receiver or soundbar is telling your speakers to do. You're upmixing audio and need to change it to "direct" or whatever it is called on your sound system in the EQ settings.
Good video, good tips. Thanks bro 👍👍
What if I have a 20x20x8 a square room. I can do the even distances but people are saying that a square room is not ideal for good acoustics especially bass response. I have dual subs btw.
does ypao or odessey mic calbibration changes this?
wow... amazing cinema sound...i have got to get that...
The speaker setup in this video is crazy
those monitors? they are designed for mixing, not for home theater usage
if my fronts LCR are 10 feet and there is no 10 feet space for surrond only 6 feet one side and 6 feet other side what will be delay
(Do delay mean distance in avr or level in avr )
Quality knowledge..
Where do you hide the wiring?
Can the speakers be ceiling mounted?
Very positive and inspiring SIGAN ASI EXCELENTE VIDEOS
good .............................
Auto-eq with time alignment fixes the bad speaker distances.
Good to speaker,nice to watch
Nice video,very good video
Man, is 2018 and av receivers can setup distance and delay, so you dont have to place speakers in the same distance of you
What about putting surrounds in the ceiling? Are there special considerations, or is the magic triangle enough?
Agree with all, but impossible to do in... example, a bedroom, where you are with your back against the wall
If you're doing a 5.1 it should be okay. It's not optimal, but it'll be fine. If you're doing 7.1, yeah you can't have your back against a wall. Small room, if one wants surrounds, 5.1 is preferable.
sangat bagus videonya memberi solusi
Wow! That surely simplified it. Now if you could please offer me some advice. I am doing 7.1. I have (3) 5.5 driver towers in front. Matching center. 2 bipole speaker and in the market for the other (2) to complete set. And I have a 10” sub. My question 1 is do I place the bipoles in rear or sides? And recommendation for the missing 2. Small bookshelf? Etc. thanks. I’m using a Yamaha R8 series receiver
VLOG MUITO TOP E MUITO BEM ESPLICADO PARABÉNS
This is an excellent video!! When I finished my basement space, I ran 7.1 wiring in a layout like you show at 3:20 (with sides at 80 deg, due to layout limitations) and it is very good for side-to-side, but the rear speakers do not seem to fill in enough to shift the effect behind the listener. I wonder if I should aim the side speakers backward, to a point behind the center position a bit, to enhance the surround effect? My speakers are at mounted 90 deg to the wall so focal point is slightly in front of listener right now, so I am wondering if it is worth getting speaker mounts to allow aiming these back. A gain of 10 degrees seems like not enough to be worth it, but if focusing back a even further would help, I would consider it. (e.g. if two people sit 3 ft apart, I would aim each side speaker at the closest person, rather then a midpoint between the listeners, for about a 20 deg angle to the wall)
Another option I was considering was to investigate if my receiver could treat rear speakers to same mix as side (e.g. 5.1 mix with "dual" side speakers), and then balance the levels (side and rear) so I could create a "virtual" speaker over my shoulder (between these). However, I do not think this is doable with my Yamaha RX-V673 receiver, and perhaps the tweak in the paragraph above would be enough, and allow true 7.1 to continue to be used.
Appreciate your thoughts/experience.
This is also assuming that the couch is in the middle of the room when 95% of the time its off the back wall, Id like you guys to talk about how the speakers are affected when this is the case. It is with me but I already combated this problem.I happen to have a 11.4 , 7.4.4 .But i also happen to have 4 heights which i can switch off with ceiling and front wides Thanks
@@cinema_sound5003 my room is 14 x 18. My room is all Def tech stuff, plus I review for AVS,so I have a constant influx of new gear. My AVR. Iss the Denon 6500 amps range from Emotiva to NAD. I can say its a delicate balance act making things give.
great video! very informative.
Hi, on 5.1 I ve put my surround speaker 1.5/2 feet above ear level, is it right? Sometime is fine, same case not. Dolby specifies this but most people say the opposite leaving surround on ear level, but they are distracting..
buena manera de aprender sobre los studios
So sound traveling at 761 mph out the speaker will sound “late”????
nice video.. you learn more.
What I think sound system is the life of music. In this creative video, they have utilized it shown properly. Best of luck from heart.
Good vlog, helpfull for me.
muy bueno el video sigue haciendo mas
What about for those of us that like to mount everything in the ceiling or wall? I have 2 round Martin logan's in the ceiling above the couch and I want to put 2 in wall behind the couch and on the TV wall
Time alignment is new for this guy
Wouldn't things like YPAO or Sony's auto calibration make speaker distance less of an issue than speaker angle?
What about the height of the speaker to listening position?
This is a good advice....!
In general what should front and rear balance be like in a mix? How much lower are rear speakers? Say on orchestra balance strings brass etc?
I'd always subtract the rear by 25% in level. They usually mix rear content too loud. That is my experience. Adjust how YOU like it.
