Perfect Speaker Placement - Put next to the back wall as much as possible.


Hello,

I happen to find an good article about the ideal speaker placement. 
(Easiest version without numbers & formulas that I can’t honestly understand :D)

I’d like to share. 

Personally I find two things interesting.

1) Only use 40% of the room area (38% rule)

2) Put the speaker as close as possible to the back-wall (next to bass trap)

Of course, minor adjustment would be required depending on speakers.
Still, I think this is helpful to figure out the very first step.

Happy listening.

p.s. what should I do with half of the room left... :?

baylinor -- you actually induced me to take a tape measure out and measure the speaker distance from the front wall.  Assuming that the 38% figure is from the wall to the speaker's business end and not from the end where the wires attach, I've found I'm within a quarter inch from 38%. No wonder my system is so world class.  If Hairy Person were still kicking, he'd give my ears a medal. I dig your Aladdin Sane avatar, too.
In thousand of years nobody has ever contested this mathematical fact, even trees obey it...And celestial dynamics are also obeying it...

: 62 is the proportion between the shorter line and the longer one....Or 1/1.6180
Just beginning in the hobby, I can’t tell you all how helpful it is to see the lack of agreement amongst those with years of experience in the hobby.  It’s takes subject matter that is critical but confusing to impossible to comprehend.  I am also stuck with long wall placement in a 33’ x 18’ room. The one bit of value that I have gathered from this ‘discussion’ is that I am best off throwing a dart anywhere in the board and starting there.  After much (confusing) reading on the subject I have sent my dart to the golden ratio.  This allows me to manage two dimensions at once (distance from side wall and distance from front wall) as one variable.  If it does not work just throw another dart.

Nothing will replace fun experiments with your own ears.... It takes times, it takes me 2 years to figure it out, one incremental acoustic controls or treatment , one step at a time...But we must all learn how to listen sound...Hearing sound is not listening sound...we must learn to be consciously active in listening sound...

And the method for becoming active in listening is simple: we create a modification in the room and after some listenings we decide if this is good or bad for our ears, this is called feed-back... One feed-back at a time the acoustic veiled marvel of your room reveal itself.... It is the contrary of a strip tease tough , the beautiful nude room is dressed by you one step at a time.....

How is the texture of this sound? How is his color? How is the decay? is it a flowing sound like a wave gently floating to my ears or a sound that seems a distant island? Are each instrument well placed and separated but anyway partaking the same ethereal space in my room? is the soud limited to a walk between the speakers? if so this is wrong...Etc....

All these impression will guide you to take the good choices... Experimenting is trials and errors...But any errors is only a step to a new joy...

You will be amazed someday, when listening music,you will be able to qualify the sound qualities and variations spontaneously on the spot... And the doubter simplistic mind must know that, NO, i dont have and we dont need hearing bat ears to do that....

The only rule is believing in yourself and having faith in your ears... Your room will be for your ears, not for the neighbour or for an audiophile bat omni hearing creature, but for you.... Take pleasure listening and think about the way you can change thing little by little and verify with your own measuring rod: your ears/brain/body....


I experienced the same desorientation 7 years ago as you.... I made mistakes listening to reviewers in my buying choices... No reviewers said to me that the only important factor are not the choice of costly gear, but the way we must control vibration, electrical noise level, and acoustical settings...

They all sell something and people wanted to pay without never making their homework.... But this homework is the only real joy in audiophile life It is listening experiments with low cost device to cure the 3 source of noise or of lost of S.Q. It is not only buying a beautiful new electronic design ...

It is creativity and music the never ending real joy....

Happy New Year...

Ok, I feel like this is an extension of another post I just made in another discussion about imaging.
 I used to sell audio, I have some experience setting up different kinds of speakers. They vary dramatically in their optimal placement from walls. So no one rule works, despite acoustic treatments or DSPing being helpful. If you have a port in the back of your speaker, it behaves differently than a sealed acoustic suspension, which behaves differently than dipoles. Some are made to be against walls or made to be placed in corners (I sold Klipsch speakers).
