The SS7747 is designed for use with the new breed of compact high-powered subwoofers that utilize a M20 x 2.5 threaded pole mount. The threaded mount improves on the typical cup design by eliminating wobble and guaranteeing a perpendicular alignment between subwoofer and pole. The system effectively eliminates the perceptible lean often associated with subwoofer-mounted satellite setups and is a space-saving alternative to tripod speaker stands. Height adjustment is easy thanks to the SS7747's folding hand crank. The pole's rack and pinion components are constructed of diecast zinc and allow for a 12" travel. The SS7747 is designed to support a properly balanced speaker of up to 145 lbs.
