In-Wall Center Speaker Recommendations

[Roughy]

I know it's possible to get the recommendation of heading to a full-on A/V forum type of place, but I like you guys, so I'm axeing the question here.

As I'm working on my basement / gameroom / etc. I'm finally at the point to where I'm ready got my sound equipment in line.

I'm looking for in-wall center speakers that will fit a standard-size studded wall (3.5" depth).

In fact, I really like these:

However, as luck would have it, the depth is like 3 7/8", which means that I end up with a speaker poking out of the wall (at least on one side).  I'd also like to stay with something that's not more than 15.5" wide.

I should also mention that I'm going to be running a 6.1 surround, so I'd want 2 of them.  And, of course, I'm looking for reasonable deals, too.

Thanks for any assistance!
