Key Features:
 JBL’s exclusive neodymium magnet
Differential Drive
®
woofer for high-
power capacity and lightweight.
 Two patent-pending neodymium HF
compression drivers.
 Constant Curvature waveguide for
unprecedented array coherence
 Fly combinations of VRX928LA and
Subwoofers (VRX915S) with optional
array frame (VRX-SMAF)
 Integral rigging hardware for simple
connection of enclosures and optional
array frame. Arrays of up to six
enclosures may be flown.
 Dual angle pole socket for aiming
flexibility. One or two speakers may be
mounted to a 35 mm pole or tripod
stand.
 Array Configuration Selector permits
“array shading” in passive mode.
Application:
 Music playback and sound
reinforcement in small to mid-size
venues.
 Entertainers, corporate A/V professionals
and sound system hire companies.
 Permanent installations.
VRX928LA 8" Two-Way
Line Array Loudspeaker
System
The VRX928LA is a lightweight
(28 lb / 13 kg) compact 8" two-way line-
array speaker system designed for use in
arrays of up to six units. VRX928LA is
the ideal choice when line-array
performance is needed but the venue
size doesn’t call for the very long-throw
characteristics of larger line-arrays such
as JBL’s VERTEC or VRX932LA.
The Constant Curvature waveguide
mounts two compression drivers on a
continuous arc. When additional
VRX928LA speakers are added to the
array the uninterrupted arc continues. In
effect, all the drivers work together as if
they were a single driver on a very long
waveguide. Since there are two HF
drivers in each VRX928LA, the combined
power handling and acoustic output of
the system is far greater than a single
driver could achieve.
VRX928LA uses “amplitude shading”
to shape the coverage of the array.
Switches on the input plate allow, for
example, the upper box in an array to
reach the distant rear of a room while
the lower box is shaded back to reduce
excessive level at the front of the
listening area.
One or two VRX928LAs may also be
used on a tripod or over the VRX915S
subwoofer. The integral rigging hardware is used to securely lock the array
together.
As many as six VRX928LA speaker systems may be suspended in a single array
for a nominal vertical coverage of up to 90°. Suspended applications require the
JBL VRX928LA-SMAF array frame (available separately). For applications in which
the array must be aimed sharply down, a second Array Frame may be installed to
the bottom of the array serving as a pull-back.
The VRX928LA is manufactured and sold under U.S. patents 5,748,760; 6,112,847; 6,394,223; 6,847,726, and D483,744.

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.
