Summary: I also found them pretty easy to install. The sound is good, but not fantastic. Although I am still trying to decide how much to blame the speakers and how much to blame the echoey (sp) nature of the room. My only real complaint is the narrow cone of audible area. I have 2 speakers mounted in my kitchen with a 255 cm ceiling. You have to be pretty close to directly under the speakers to hear them well. I have 4 mounted in my living room at 310cm height.
Summary: They sound good, can turn them up pretty loud. Sound just a tad bit flat, that is the reason why they got 4 stars. Overall they do the job and music is played fine with no issues sounds clean and they work well.
Summary: Great value for the money and excellent sound the tweeter can be adjusted by hand to give a more accurate sound. Easy to install template and everything was easy to use. These have to be the best sounding in wall or ceiling speakers. In ceiling installation.
Summary: I was looking for ceiling speakers and have always been an Infinity fan, but the price on these got my attention. Overall they sound great, although front channel imaging is never as good when coming from the ceiling as opposed to directly in front of you, but ceiling mounting was what I needed in this application. Great value!
Pros: Easy to install, good quality, good overall sound quality
Cons: Tweeter imaging is good but not perfect....still a high recommendation for the money!
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.
