Here's another way to think of it, your entire room becomes the inside of a speaker, so to say. Alot of speaker companies try very hard to design unique cases to stop standing waveforms(Axioms design does this) so if your room is perfectly/evenly shaped you could have this standing waveform problem.

"12ft x 12ft x 12ft is not good 24ft x 12ft x 6ft is not good 22ft x 12ft x 8ft YOUR room, I don't think you will have too many problems, unless you have bare walls." But these have a common devisor by 2's. Or 21x12x9 by 3
Isn’t the idea to have no divisible lengths...... 23x13x7 or 23x12x7 or 19x11x8?

Troy, the significant factor actually isn't not having a common divisor, but rather not having the dimensions be the same or exact multiples of each other. So, the 22'x12'x8' room dimensions all being divisible by 2 isn't significant; they have the relationship of 2.75x1.5x1, which is okay.

It is also important that the numbers aren't divisable by themselves easily
12 does not go into 22 8 does not go into 12 or 22

If you're fundamentally lazy like me, you can download the "Graphical Mode Calculator" from Ethan Winer's "RealTraps" site, plug in some room dimensions, and look at the graphs to see how the different room resonances pile up at different frequencies. An ideal room has the resonances (modes) evenly spaced. Nobody has an ideal room unless it was designed and built from scratch for audio use, so don't worry if they bunch up in a couple of places. Those will be the "problem" frequencies and you can do things with subwoofer placement to help with them. http://www.realtraps.com/info.htm
