As your room gets bigger, the first reflection points and bass trapping get less critical. The idea of damping the first reflection points is that it helps the stereo imaging.

Imagine a snare hit in the left speaker that goes straight to your head and goes and bounces off the left wall and reflects back to your head. If these two sources of sound arrive close together (within about 20ms) then your brain doesn't differentiate between them very well and you get smearing.

So, you want to damp out the reflection. These reflections happen on walls, ceiling, and floor (and coffee table, and cabinet door and ....). But, if the wall is about 10 feet away from your head or more, the delay is long enough that it is less critical. Alternately, you can set up across a corner and the reflections won't reach you (because the angle is wrong). This has other problems in small rooms, though.


Then there's the bass thing that you already seem to have a handle on.

Thanks, Tiny. I knew about the first reflections thing, just wasn't financially able to do anything about it until now. Maybe someday humans will evolve to where their brains can filter out 1st reflections - perhaps with a muscle contraction accompanied by a small grunt. But those future humans would most likely have to be descended from today's cave-dwelling audio engineers.

Something to chew on.. or not.

By the way, owl poop is really slick when it first comes out.
