JBL VRX918S 18" High-Power Passive Flying Subwoofer Black

The VRX918S is a compact, high-power suspendible subwoofer system containing a 2268H neodymium magnet, patented Differential Drive, 18" woofer in a front-loaded, vented enclosure. The VRX918S was designed specifically for use with the VRX932LA Line Array speaker and VRX-AF Array Frame. In addition, it may also be used in setups consisting entirely of VRX918S subwoofers.

The subwoofer 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.

Equally at home in ground stacked applications, the VRX918S speaker 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 35 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 VRX918S 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 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 speaker enclosure is fitted with T-nuts which may be used to attach the optional WK-4 caster kit (sold separately).
