Very nice, I actually own a set of these and won them from a karma drawing on Polk Audio's forum. Mine are demos. These demos were actually frozen in a block of ice, among other things. If someone didn't tell me, I would swear they were brand new. They sound perfectly.
Easy Install, Sounds like Polk brought their inside voice outside; Very clear and crisp, you actually hear sounds you never heard from the competition's speakers; Nice thump as well; Fills up my backyard with perfectly sounding music
I am not always out back to listen to them
