Quadra™ 15 - Black

15″ Two-Way PA Speaker


The Quadra™ 15 is an injection molded two-way speaker system, engineered in the AA tradition to provide superior performance from a compact and durable package. The enclosure is made from very high impact injection molded polypropylene in a trapezoidal shape, with extensive ribbing and bracing, and the grilles utilize perforated metal protected by a high quality vinyl coating process, and has an integral foam inner layer for environmental protection. The two-way system is comprised of a 15″ BWX Black Widow® woofer with a 4″ voice coil, and a water-resistant treated cone and dust cap for superior environmental stability. The high frequencies are handled by an RX™22 two-inch titanium diaphragm compression driver utilizing ferrofluid, coupled to a 1″ Quadratic Throat Geometry Horn, molded integral to the cabinet. This horn provides outstanding dispersion coupled with a well-controlled pattern, and a smooth, even response.
