SVS PB3000 Active Subwoofer 800W RMS 2500W Powered 13 Sub Home Cinema Black Ash
Beware, this is stupid heavy and needs two to lift. Subwoofer SVS PB3000 and power cable is what you're purchasing. And yes, this infra-woofer is unreal. PB-3000 features two port tuning modes, each with individual response curves to achieve the most accurate in-room frequency response possible whether in sealed or standard mode.
