VRX918SP
18" Bass Reflex Powered Subwoofer
Key Features:
䉴 Built-in JBL DrivePack® DPC-2 amplifier module designed by Crown provides 1500 Watts of peak power. DSP based resident input module provides system optimization, EQ and crossover functionality. 䉴 18 inch, 2268FF dual voice coil, neodymium magnet Differential Drive® woofer for high-power capacity and light-weight. 䉴 Integral rigging hardware for simple connection of enclosures and optional array frame. 䉴 20 mm threaded pole socket for solid, secure satellite speaker mounting. 䉴 Large port area for reduced distortion.
Applications: 䉴 Music playback and sound reinforcement. 䉴 Entertainers, corporate A/V professionals and sound system hire companies. 䉴 Permanent Installation. The VRX918SP is a powered, suspendable subwoofer system containing a 2268FF neodymium magnet, patented Differential Drive®, 18" woofer in a front-loaded, vented enclosure. The VRX918SP was designed specifically for use in arrays with the VRX932LAP Line Array speaker and VRX-AF Array Frame. In addition it may also be used in arrays consisting entirely of VRX918SP subwoofers. Equally at home in ground stacked applications, the VRX918SP 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 and weighing up to 50 kg (100 lb). 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 in JBL’s rugged DuraFlex™ finish and is heavily braced to maximize low-frequency performance. The attractive CNCmachined, 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-4S caster kit.

JBL continually engages in research related to product improvement. Some materials, production methods and design refinements are introduced into existing products without notice as a routine expression of that philosophy. For this reason, any current JBL product may differ in some respect from its published description, but will always equal or exceed the original design specifications unless otherwise stated.
