Summary: I upgraded my rear surrounds and decided to go with ceiling mounted speakers and these do not disappoint. The most difficult part of installation was crawling in the attic and running the wires, but that was expected. If you decide to go this route, plan for a cool time of year. Once installed, these speakers filled the rear of my living room with solid, clear sound.
Pros: Price, sound, quality and easy installation.
Summary: These Polk Audio's are the best speaker you are going to find in this price range. Mine had a little bit of a break in period but came to life pretty quickly. 4 stars because I know you can get speakers that do sound better but if you are an average user these will more than exceed your expectations.
Pros: Price & Sounds
Cons: Install. I've installed a few different types of in-ceiling speakers and the brackets that hold them up in the ceiling were a little difficult to work with. Not so much so that I wouldn't buy them again, however.
