The VRX918SP is a powered,
suspendable subwoofer system
containing a 2268FF neodymium magnet,
patented Differential Drive
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.
