I own the PA 150 along with Epik, Chase, Klipsch, SVS and some other brands. The PA 150 is one of my favorites. It sounds nice for movies and music and is a output monster for a large room. The only complaint is that it does not have the extension of some more expensive sub. But, at it's price point I don't know of many better subs. It is not one of the major brands but it is well built and the larger the room, the better decision points to the PA 150. With room gain, there is good usable extension into the low 20's.
