VRX-928LA

LINE ARRAY SPEAKER

Line-array Cabinets from Industry-leader JBL!

While intended for smaller venues than the VerTec series the VRX928LA Constant Curvature
Line Array is designed and built to the same high standards and uses the same advanced
concert-proven drivers. The VRX928LA delivers extraordinary power handling clarity
flexibility and of course stunning JBL sound in an attractive easy to handle and affordable
package. The VRX928LA is a perfect fit for medium-sized venues that don't want to sacrifice
sound quality just because they're not as big as other professional facilities. For compact
power it's the VRX928LA.

JBL VRX928LA Line Arrays at a Glance:

  • Lightweight and built for smaller venues
  • Great power handling and sound
  • Flexible mounting options

Lightweight and built for smaller venues
The VRX928LA is a lightweight (28 lb.) 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.

Great power handling and sound
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.


Flexible mounting options
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.

JBL VRX928LA Line Arrays Features:

  • JBL's exclusive neodymium magnet Differential Drive woofer for high power capacity and lightweight.
