    After a couple of months using it in the garage it started to make a sqeaking sound. Broke it in below half volume for like 10 hours to make sure it didnt do this. But good bass and sound while it didnt sqeak.

    I've always been impressed with the Sound Polk Audio puts out. I had to replace my Polk Sub of 20 years with this one. This one sounds just as clean with great thump for the room. Highly recommended

    The subwoofer is strong but is larger and probably way more than we needed.

    Buy it! It’s worth every penny you pay for it. Drops super low and handles punchy bass awesome as well. Get permission from the wife though bc it’s gonna knock pictures off the walls.

    Works great with a Sony - STRDH590 in a 5.1 setting and Polk satellite speakers. Nice and solid bass that fills my entire basement entertainment area.

    This sub is good value for money! It rumbles and shakes the wall clock in action scenes. Vastly improved my listening experience. Highly recommend. Faim @ BestBuy Allen was a pleasure to work with, very helpful.
