Well, I bought the Speakercraft Cinema One's for the LRC locations.
There doesn't seem to be much, if any, review of these speakers so I hope this helps someone.
The build quality is excellent. You can tell attention is given to detail.
Installation is easy. I had holes and wire already there from my Boston Acoustic DSi 260's, so that made it easier. You can angle the mid-high range speakers toward the listening area. Awesome advantage, since they are in-walls.
The sound quality is amazing. They will break in over time, but the initial sound quality is great. They truly give the (full) sound quality you would expect from tower speakers. The Boston's were great speakers but lacked in the mid to low range and had to rely on the sub. With these, the sub is basically backup for a richer sound experience.
For the price, trust me, I've researched this, you can't do much better.

The only thing you have to check is the room on the wall. They are large (long) but have to be to accommodate the 4 speakers.
Hope this helps someone.
