The original Vandersteen subwoofer with attractive walnut top and bottom caps and black grill cloth. This subwoofer can be used with any pair of speakers but connects into your system by tapping a signal off the speaker outputs of your amp. Comes with a selector box that installs between your amp and preamp and implements the high pass filter. The low pass filter is inside the subwoofer. Provides really powerful and clean bass with its built-in 300W amplifier and three 8-inch slot-loaded woofers. I am the original owner and can ship in the original box, however local pickup in Southern California is preferred as shipping cost could be high (subwoofer weighs 80 lbs.). There is a faint stain on top from a water glass but its not too obvious. Accounts for the 5/10 condition. Other small scratches and snags in the grill. Included at no extra charge is a pair of fixed crossover assemblies from Vandersteen suitable for 50 kohms or higher amplifier input impedance. These normally cost about $100. Paypal adds 3%.
