Slammer,

> I'm just confused about the property of standing waves/room modes that makes them independent of speaker position <

Take an empty soda bottle and strike it gently near the mouth with the blunt end of a drum stick. Now strike the bottle again on the side, and again at a few other places. The basic pitch is always the same, but the tone will change as different partials are excited. The same thing happens when a loudspeaker (the stick) excites a room (the bottle). The basic resonant frequencies of the room stay the same, but depending on where you "strike" it you'll get different proportions of overtones.

TS:

Here is a resource that will link you to a number of texts and online acoustics journals that might be of interest.
