This subwoofer works fine and is in very good condition. There are very minor, hardly noticeable scuffs or nicks on the piano black top cap. Fabric is in very good condition.

Also this subwoofer has a NEW preamp plate that was replaced recently. Original preamps were known to have problems so buy with confidence. Other used Supercube III sold here on Ebay probably  are using the original preamp plates that were known to be faulty.

For a subwoofer the size of 10x10x11 in. cube, it delivers deep base.  It has high level inputs and outputs rarely found in subwoofers of this size. This allows connection to receivers that don't have preamp or subwoofer out. Also, getting two of these subwoofers will fill a room nicely to get the best sound possible.
