Yes, I know. I design studios too. Trust me, you don't have the room to splay the walls enough to do more than mess up calculations. To make a dent, you'd lose about 28" of width at the front of the room. Not worth it. It would cramp the screen, mess up speaker placement, etc. Remember, studios are NEARFIELD listening environments. This is not.

Also, even though that gets rid of direct slap, it still does nothing to reduce decay times. That just requires absorbtion. You'll still have standing waves, just a matter of where they are and at what frequency. There are also other modes which involve 4 and 6 surfaces.

Sorry
Thank you for the quick response! OK, I see your point about studios being nearfield. but performance spaces are not, and I see many newer halls with a "keystone" shape and non-parallel back wall. And even older theatres often have a keystone shaped stage with a rectangular seating area. Also, you mentioned messing up the calculations. I assume pros use some kind of room response prediction software. Can these packages handle non-rectangular rooms? Finally, I agree, too much room reverberation is a mess, but a little can be helpful. The other day I was testing some headphones, and the Steely Dan song "Black Cow" was available, so I listened. On headphones the opening sounds completely dead! tons of reverb is added later in the song, but the opening needs some room response to sound decent. So it makes me think that a little bit of room response is not a bad thing. It might even allow people to get away with smaller subwoofers and less overall audio wattage.
