Is an eight sided oval room acoustically correct?

Maxgain: The tube traps will help. The other option would be to use heavy drapes but just close them enough so that the angled portions of the window are hidden from view. Then the plant does help with diffusion and you've minimized if not eliminated the bay window focussing issue. The drapes would probably look nicer than the tube traps and might get siginificantly better spousal approval ratings.

Thanks Rives. The damn plant is so big that it sticks out two feet out into the room, so curtains are out. My wife already thinks I'm nuts and since this is the basicly the Hi Fi room she doesn't say much about what I do in here.
This is more or less my room. I am the one that isn't into uglying it up. It's nice to have a listening space that isn't so bizare looking that no one but me feels comfortable in it. I would probably choose the 9" full rounds in a light fabric so they wouldn't call a lot of attention to themselves.

Have you seen the Golden Sound Acoustic discs? Odd little critters. I wonder if they work?

Rives, I have some Swiss Felco's(pruners) but I guess I like the jungle effect and more leaves = more diffusion, right? Just for fun, what do you think of that new Shakti "hat rack". That is a bizare looking contraption. I can imagine a room all done up in RPG stuff, Tube Traps every where,several Argent Room Lenses and a few of those crazy looking Shakti things! Talk about WAF!

Joeb, thanks for the info on psaudio. It looks like I can build those four 3.5 foot "walls" in each corner of the room and construct a bass trap as well. Great idea!
Rives, thanks for all your help at your "listening room" website above. It's great to know that I can get professional help just a few miles away in Jessup, MD. I'm just around the corner in Annapolis.
The biggest problem that I see now is where to place the K-horn speakers in the eight sided room. Obviously, each speaker is going to need two 4x4 foot false walls for the bass. Won't pulling the speakers and baffles out one third the length of the room interfere with sound staging, etc?
