Subwoofer
The 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 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 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 in JBL’s
rugged DuraFlex™ finish and is
heavily braced to maximize lowfrequency 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.
The VRX915S is manufactured and sold under U.S. patents
5,748,760 and 6,847,726.

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
