Here is a unique subwoofer that has been designed to be invisible because it can be hidden in ceilings or walls. The complete BPS-1 Bandpass Subwoofer System consists of a BPS-1 bandpass subwoofer cabinet, an Adaptor Baffle, a dedicated Sonamp A150 power amplifier, an Architectural Series Panel Bracket and an Architectural Finish Component. All of these parts are sold separately. [Product Page]
