I read several reviews from several sites before i purchased the Polk Audio Atrium 4- most of them gave great reviews. I mounted them on my deck about 7 feet in the air under the deck roof about 30 feet from the house (and amplifier). Installation was very easy and the mounting brackets are quality and versital. The sound quality was excellent at any volume. I also installed a volume control outside (highly recommend). The speakers sound great and the bass is sufficient- I think it helped increase the bass by placing the speakers closer to the ceiling. I definitely recommend these speaker. My wife even approved!
