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.

I read an article on the net some months ago about acoustics of small room.... The article is no more there where i read it... It was a discussion with 4 great well known acousticians, they speak politely, were in accord about many things but surprizingly used very different approach to similar problems and seems to disagree at some point...

I was amazed and conforted in my improvised ears listenings experiments at the times creating my own controls devices for my room...

Acoustic is a practical art, ears are needed, and any small room is a unique problem that cannot be OPTIMALLY solved most of the times by simple rule...

The proof that it is so, was for me this disagrement between these specialists very palpable in the discussion...

Alas! the article is nowhere to be found and i dont remember the names... I remember only that it was a discussion at McGill university ...

ALL depends about the room . Period .
I saw a setup where one speaker pointed to the wall and one away from
it was best .
In a perfect world your room dimensions would be 14.5 X 23.5 X 9'. That gets you the Golden Ratio in all 3 dimensions, and a good starting point. Unless you use the Bolt method, in which case it's off the chart. Go figure. Literally. You still need to calculate and deal with the eigenmodes in those 3 dimensions plus axial, tangential, and oblique. Like this:
