I just got done framing my new HT... you're making me feel the need to tear it down and start over.

Naw, Chris; for example, Dr. Toole, in Sound Reproduction at p. 203("Optimizing Room Shape and Dimensions")states: "A recurring fantasy about rooms is that if one avoids parallel surfaces, room modes cannot exist. Sadly, it is incorrect". In the following pages are computed pressure distributions in non-rectangular rooms, showing irregular patterns of high and low areas. He further comments(p.204)that "The real difference is that in rectangular rooms, the patterns can be predicted using simple calculations".

Enjoy the music, not the equipment.

After I typed that, I started wondering what the pressure wave distribution would actually look like in a horn shaped room. It made my head spin a bit, and I did start to doubt that there'd be no ill effects at all.

So OK. Normal, boxy room with major dimensions that are not multiples of each other, and treat with bass traps. No more fantasies. smile
