While intended for smaller venues than the VerTec series, the VRX918S is designed and built to the same high standards and uses the same advanced, concert-proven drivers. The VRX918S delivers extraordinary power handling, clarity, flexibility and, of course, stunning JBL sound in an attractive, easy to handle and affordable package. The VRX918S is a perfect fit for medium-sized venues that don't want to sacrifice audio fidelity just because they're not as big as other professional facilities. For compact power, it's the VRX918S.
JBL VRX918S Line Arrays at a Glance:

  • Lightweight and built for smaller venues
  • Flexible mounting options
  • Enclosure built for optimum performance

Lightweight and built for smaller venues
The VRX918S is a compact, high power suspendable subwoofer system containing a 2265G-1 neodymium magnet, exclusive Differential Drive, 18" woofer in a front-loaded, vented enclosure. The VRX918S was designed specifically for use 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 VRX918S subwoofers.
Flexible mounting options
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 VRX918S 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.
Enclosure built for optimum performance
The enclosure is constructed of top quality birch plywood, coated in JBL's super durable 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.
