Just Picked up the sw112 at a Local a/v store out of Vero beach,Fl ,I listen to the martin Logan and the difenttech and tell you for the Price this sub is a great product! I have a pair of klipsch rf3 II and a rc3 II center but was using a infinty sub, Finally the sub went bad, but I tell you that the sw112 truely has made a big diffrence....the bass goes very Low with no rattle and no distortion. but you feel the bass right in your chest.,..I am useing a yamaha avantage 1000 and what a greate system I have Now....I now that paridige and velodyne make great subs but hard to find to sample...anyway will recommend this sub to anyone..great job Klipsch.....NN
