Buy Jim Smith’s book Get Better Sound.
Read it, then read it again.
Get your positions of speakers and listening seat established.
Do room treatment.
Enjoy how much better your system sounds.
Enlighten others.
Whoa! What?! Back up! The speaker locations will change as you apply room treatments. That’s because the dynamics of the acoustic waves changes as you treat the room. What you have to do is use the speaker location track of XLO Test CD. Then you will be able to find the single absolute best speaker locations, assuming a given listener location, not some guesswork.
However, as room treatments progress the 3 D dynamics of sound changes. That’s why you have to re-establish speaker locations every once in a while with the XLO CD. Trying to find the absolute best speaker locations without the XLO Test CD, trying to do it by ear, is like trying to solve 3 simultaneous equations in 4 unknowns. 😬
In any case reverse the order of establishing speaker and listening positions and applying room treatments shown in the previous post.
