Summary: Sounds super, I'm using this with 4 625RT fronts and RM8 surrounds with 2 660 powered sub. The grills look even better then I hoped for, so thin and clean. They carry mid and high's very cleanly. The mid bass is tight and accurate and work very well with the 12" Polk powered sub 660wi.
Summary: Great option if you don't want large speakers sitting on the ground. Created a very clean look in the wall and the sound in my opinion was just a good as traditional towers because the other speakers installed with it (5.1) complemented very well. Easy to install.
Pros: Good sound, easy to install, reasonable price
