Northridge, CA (April 6, 2012)—Harman's JBL Professional has expanded its next-generation VTX line array series with the addition of two subwoofer models, the VTX S28 and VTX G28.
The VTX S28 and G28 are dual 18-inch subwoofers, each employing two 2269H 18-inch transducers featuring Differential Drive technology with two voice coils, two neodymium magnets and peak-to peak excursion capabilities to deliver extended low-frequency performance. Both models are reverse-cardioid-arrayable.
The VTX S28 can be suspended or ground-stacked and is cardioid-arrayable in either configuration. Compatible with VTX V25 suspension, the S28 can be suspended at the top of V25 arrays to extend the effective low-frequency line length, providing improved vertical pattern control combined with improved rear rejection when used in cardioid mode.
The VTX G28 is ground-stackable, but with a form factor for stacking and additional enclosure volume, plus port tuning that reportedly delivers sub performance down to 22 Hz @ -10 dB.
Like all VTX Series models, the S28 and G28 feature Crown Audio VRack DSP and amplification. VRack is a touring rack fitted with three Crown I-Tech HD Series power amplifiers, power input panel and custom-engineered input/output panels that is available in two configurations: VRack 12000 and VRack 4 x 3500 are loaded with three IT 12000HD and three IT 4 x 3500HD amplifiers, respectively.
VTX's patented S.A.F.E. suspension system is streamlined for "speed and efficiency, with improved hardware for faster setup with fewer pinning operations and greater security." Vertical transporters will be available allowing for transport of four V25 enclosures or three S28 enclosures in either front-firing or cardioid mode.
