The new VRX932LAP 12-inch, two-way powered loudspeaker and the VRX918SP 18-inch powered subwoofer are both powered via built-in JBL DrivePack DPC-2 amplifier modules designed with Crown. Both models feature onboard digital signal processing for system optimization and equalization.

The VRX932LAP features an onboard DPC-2 amplifier module that provides 1,750 watts of peak power. With three 2408J Annular Ring Diaphragm HF drivers, the VRX932LAP is the first product to feature JBL's 2408 compression driver design. The VRX932LAP’s Constant Curvature Waveguide mounts three compression drivers on a continuous arc. When additional VRX932LAP loudspeakers 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. Because there are three drivers in each VRX932LAP loudspeaker, the combined power handling and acoustic output of the system is far greater than a single driver could achieve.

The VRX932LAP uses “amplitude shading” to shape the coverage of the array. For example, switches on the input plate control the output of each high-frequency section in the array. This allows users to set the upper enclosures in an array configuration to deliver more output to reach a distant balcony, while the lower box is shaded back to reduce excessive levels at the front of the listening area.

One or two VRX932LAP loudspeakers may also be used on a tripod or over JBL VRX918SP, VRX918S or SRX718S subwoofers. The integrated rigging hardware is used to securely lock the array together while the dual-angle pole socket provides aiming flexibility. Suspended applications require the JBL VRX-AF array frame or eye bolts.

Designed specifically for use in arrays with the VRX932LAP, the VRX918SP is a powered subwoofer system containing a 2268FF neodymium-magnet patented Differential Drive, 18-inch woofer in a front-loaded, vented enclosure. A DSP-based resident input module provides system optimization, EQ and cross-over functionality.

The VRX918SP is equally at home in ground-stacked applications and is equipped with a top-mounted, threaded 20mm socket that can receive the optional SS4-BK pole. The VRX918SP’s 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 CNC-machined, 16-gauge steel grille is internally lined with acoustically transparent foam to provide additional driver protection. The rear of the enclosure is fitted with T-nuts that may be used to attach the optional WK-4S caster kit.
