I very much like three channel. It gives the image a solidity that the two-channel phantom image can never have.

I wonder if a bit of left-right mixing as in headphone listening would solve the problem.

Did you notice it on anything else?

Reminds me that when I tried it, the only recordings that didn't work were those Beatles recordings that are mixed hard left and right! Without something in the other channel, the sound moved way forward to where the sidewall reflection was.

What you said about wavelength is true for omnidirectional speakers. But in the case of dipoles, the rear wave is out of phase and so still cancels at the sides, maintaining the figure eight dispersion pattern even when the wavelength is larger than the driver. The sound still diffracts around...

Hard to know what's causing it but I'm thinking that it could be interference between the reflections off the front and side walls, which are out of phase in the 3.7's but not in the dynamics.

I actually first tried (discovered independently) Rooze using my old Monsoon computer speakers. It was amazing to get that huge soundstage from two tiny panels! My best guess as to how it works is that it increases the acoustical size of the room since you're listening to the sidewall...

Heavy carpet out from the wall actually isn't a bad strategy. Taking it off the wall moves it out from the pressure zone, extending the absorption down into the bass. Heavy curtains can be used for this. For professional broadband sound absorption on the cheap, just get some Owings Corning...

:-)

FWIW, carpet just makes the room sound dead. And it's too thin to absorb at lower frequencies, so it attenuates the highs as well. Diffusion makes a room acoustically larger, without gobbling up the highs or making it sound dead. One way to think of it is that it transforms the room reflections...

Amazing room! Your experience with Rooze is very much like mine. For me, the amazing thing about Rooze was that it transported me to the original acoustical environment in a way that no other setup ever has. But I had the same issues with image placement that you did.
