Definitive Technology UDSA In-Wall RCS II Referance Ceiling L/C/R (Single, White)

These speakers are 14 3/8" square and that's just small enough to fit between the ceiling joists. There is little wiggle room, so installation was a bit challenging at times for me. Once installed, I was extremely impressed with the sound. It really does sound like the speakers are on the wall and not in the ceiling. These speakers also produce a nice full range of sound...even if I turn my sub-woofer all the way down. Although these speaker were tough on my wallet, I really am happy with how they sound...and I love that they are hidden away in the ceiling. The build quality of these speaker is really nice. I've never seen a more solid speaker box. If I was being a bit nit-picky, I would say one con is the grill. It's just hard to get it fit to the speaker evenly.

I'm using as my center channel in the ceiling as a last resort because I had no place to mount a center channel on the wall. I'm glad I went with this. It doesn't blow my mind, and I wish it cost less, but it does seem to throw the sound down because of the angle of the speakers, solving a huge problem that I was worried about in our theater setup. I ended up cranking up my center channel volume a bit and now it seems perfect.It's constructed really well and came with good instructions and template to cut out drywall. One of the screws broke inside the ceiling joist but we ended up being able to drive a drywall screw in that hole to make up for it.

Sounds amazing!!! The speakers are heavy and require custom installation with 2x4 for ceiling mounts, but it’s worth it.

Great speakers if you have the depth above the ceiling
