Have 3 of these for the front left, right and center behind the screen powered by an Onkyo 818 and four ceiling mount RSS II's with a SC6000 subwoofer. Stayed loyal throughout on the speaker side and very happy with the speaker performance. Also covers are easy to paint and install.
The AV guys tell me this is not a true bipolar, but it works great for my surrounds. I do no know what they mean. Their range and volume is extremely satisfying. They were easy to install and in a box config, and solid. Love them.
I bought these speakers not realizing that you must screw them into the ceiling joists. That's fine, but the dimensions are less than the standard 16" center that our homes are built with. So, you are required to add some framing up in the ceiling so that these speakers can be secured in the ceiling. Thankfully, it wasn't too hard to add a bit more structure up in the ceiling, so these speakers went in pretty easy. The sound is incredible. I'm very happy with the size and look of this speaker too.
