curved diffusors

What do you think about cylindrical diffusion? I've heard mixed reviews about it's effectiveness. I'm thinking about taking some 8' x 2' corrugated plastic panels, bending them into the desired arc and standing them on end, side by side on the back wall of my live room. What do you all think?

Well, it's close to diffusion, but not quite. It's a good idea to break up parallel wall situations. They're still reflectors- curved reflectors, but still reflectors.

If you're just trying to kill off flutter echoes, this will probably work for you.

I should have clarified that I'm in a rental so I can't do any construction or deface the walls. I have 24 4' x 8' x 4" 703 panels to absorb nasty reflections and trap bass. It's just that my 24' x 12' x 8' live room sounds pretty dead once all the nasty reflections are gone, so I'm hoping to turn some of those nasty reflections into beautiful reflections.

Those absorbing panels will do a lot for you if you put them in the right spots. Do you have these set in wood frames? If you set them in wood frames, and put wood slats across one face with spaces between, but open on the other, you could just arrange them with more wood facing the room to make it more live, or more insulation to make it more dead.

And then you can take 'em with you when you move out.

That's a really good idea. Thanks man. Anyone else care to chime in on how curved diffusers have worked you?

I've used 1/8 inch masonite as a polycylindrical diffuser/basstrap in the corners of my control room. Installing an 8 ft x 2.5ft slice bent into wood slats left and right which holds the masonite in and arch without nails, gives a curved diffusing surface while serving as a corner bass trap. It should be thin enough to vibrate like an ear drum from low frequencies, which means don't put anything other than a coat of paint if ever to keep it vibrational. top and bottom of the masonite should be kept open.
