The JBL VRX915S is a compact, high power suspendable subwoofer system containing a 2265G-1 neodymium magnet, patented Differential Drive, 15" woofer in a front-loaded, vented enclosure. The VRX915S was designed specifically for using in arrays with the VRX928LA Line Array speaker and VRX-SMAF Array Frame. In addition it may also be used in arrays consisting entirely of VRX915S subwoofers.
The system offers complete input connection flexibility for compatibility with a variety of cabling schemes. A recessed, external switch allows selection of either contacts +1/-1 or +2/-2 to be routed to the woofer.
Equally at home in ground stacked applications, the VRX915S is equipped with a top-mounted, threaded, 20 mm socket that can receive the optional SS4-BK pole. This adjustable height pole can be used to mount speakers equipped with standard 36 mm pole sockets. The threaded socket minimizes buzzing and rattling and assures that the pole will be secure and straight.
The enclosure is constructed of top quality birch plywood, coated with JBL's rugged DuraFlex finish and is heavily braced to maximize low-frequency performance. The attractive CNC-machined, 16-gauge steel grille is internally lined with acoustically transparent foam to provide additional driver protection and give a very professional appearance. The rear of the enclosure is fitted with T-nuts which may be used to attach the optional WK-4 caster kit.
