Help Soon - Martin Logan surrounds

Thanks guys.
I'm specifing speaker wire thru front/center cloth AND allowing room behind cloth to experiment with front center placement.

The B&W surrounds are pretty decent. They will be located
about 4 feet behind viewers on side walls and I can adjust angle for best listening. Room is 24'x33'lg.
I have a B&K Ref 30 that will adjust for tone but I'm not sure if each speaker has it's own adjustment. Will investigate and installer is a real professional that knows B&K. Installing a Seleco 300 projector with a Greyhawk screen.
Does anybody have a site for a ceiling projector sound cover?
I am also buying 2 Velodnye CHT-15 subs for behind cloth placement. Would have bought the Martin Logan but cannot place out in room. The CHT's are a compromise and only cost $1,500. Contractor has penciled in a NAD DVD 3800.
From the reviews and reading posts I'll be a happy camper.

Good fortune to all.

Sorry - mistake.
The DVD is a Denon 3800-2.

Just a follow up. The Energy Veritas 2.2's worked out VERY WELL in my theater set up. Some will say use ML surrounds or nothing, but they obviously have dedicated rooms or dont have wives who care about having company over. The 2.2 are very nice looking in black.

I have ML Scenarios for my surrounds, and of cousre they work well with the Odyssey/Cinema fronts. However, I disagree with the claim that ONLY MLs work well - my previous surrounds were Triad Silvers. They are dipole cone speakers that are designed for in-wall mounting. They worked a lot better than you'd expect from all the discussion, with both my previous Aerius i's and the current Odysseys. Note that this for HT.

Matching for HT is, in my opinion, overemphasized, because on HT there is frankly little to choose from between the Scenarios and the Triads.

However, I do have a little bit of surround music (several DVD-As and a handful of SACDs) and there the difference is much greater. For surround music I might well agree that only the MLs will match ML mains.

Try a pair of used Maggie's or apogee's. You can find them cheap.
