I'm afraid centering was never going to be an option, so I'll have to put up with a few audio problems. Once I get the shelves built on the left side, I'll do an analysis of the acoustics and see what needs to be done.
Behind the screen is a cavity about two feet deep. The back wall is a stud wall with drywall on the far side (one wall of the shop behind it). On the theater side, I put denim insulation between the studs, and covered that with the same fabric (I still have plenty left over). Yes, the speakers are tilted toward the opposite listener's position, and the center is tilted up a bit, although it's not as far off-axis as the other speakers would be.
The DSP6000s clearly needed a larger room than I have to provide them with in order to achieve their best. These speakers were ranked in Stereophile magazine's highest "Class A" review category for years. But after trying to tame their bass for years, I just never managed to come to terms with them in my dedicated music room. To achieve acceptable mid-bass I was forced to cross them to my Seaton subs at 80Hz. This despite the flagship Meridian's being only 3dB down at 25Hz themselves. Even then the mid and upper bass was still a little woolly sounding.
