This is the second one that I had bought. I recently bought a Sony 5 ch HDMI home theater system with one of these subs. The system was is made for dual subs and was pushing too much power to the single sub causing distortion. This second sub evened out the power & now the quality is fantastic! When the levels are set just right, I hadn't had such good quality bass.
