For the critical listener looking to get the most from their music, the diminutive Model Subwoofer® speaker extends the Model Two® stereo, Model Three® clock radio, Model 10TM clock radio, and The NetWorksTM Global Audio System"s bass response by a half-octave. The Model Subwoofer speaker"s 5" bass driver, 20 watt internal amplifier, front ported design, and wood cabinet all translate into rich, musical sound. "The Model Subwoofer is designed not as a window rattler, rather to more subtly enhance the music to which you are listening. That it does, giving the music just that little additional definition that makes you notice the beautiful sound of the music." (PC Review) The Auto On/Standby circuit, an unusual feature for a subwoofer of this size, activates the subwoofer automatically when it receives a signal and places it in standby when the signal is absent. The cosmetics provide a perfect match for all compatible Tivoli Audio® models. Connecting cable and 9" power cord included
