FRANKFURT, Germany – At Prolight  & Sound 2012, HARMAN's JBL Professional is expanding its  revolutionary next-generation VTX Line Array Series with the addition of  two subwoofer models, the VTX S28 and VTX G28.
“In  January, JBL introduced the first product in the VTX Series—the V25—and  the new S28 and G28 subwoofers provide system technicians with a wealth  of configuration options and unprecedented performance,” said Paul Bauman,  Senior Manager, Tour Sound, JBL Professional. “These new models truly  represent a breakthrough in subwoofer design.”
The  VTX S28 and G28 are dual 18-inch subwoofers, each employing two 2269H  18" transducers featuring Differential Drive® technology with two voice  coils, two neodymium magnets and extremely high peak-to peak excursion  capabilities to deliver world-class, 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 for improved rear rejection. 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.
Alternatively,  S28 arrays (cardioid or front-firing) can be suspended beside or behind  V25 arrays. For theatrical sound design, the S28 can be suspended in the middle of flown V25 arrays to facilitate balcony and floor  coverage by allowing improved under-balcony penetration. Larger cardioid  configurations are also effective where S28 is suspended or  ground-stacked in multiple cardioid blocks, each block consisting of three enclosures.
The  VTX G28 is ground-stackable, but with a practical form factor for  convenient stacking and additional enclosure volume, plus port tuning  that delivers true sub performance down to 22 Hz @ -10 dB.
Like  all JBL Professional products, the VTX subwoofers are comprehensively  tested in JBL’s power testing facilities. Unique in the industry, during  the design phase JBL power testing submits each component and system to 100  hours of continuous, high level input, ensuring that your system will  deliver extraordinary sound even after years of hard use and thousands  of hours of performance.
Like all VTX Series models, the S28 and G28 feature Crown Audio VRack DSP and amplification. VRack is a rugged 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.
Apart  from the performance advantage of a standard package ensuring that VTX  Series enclosures are optimally powered and processed, VRack ensures  compatibility for cross rental between VTX Network Partners. Since VRack is supplied  with all components installed and internally connected, there is also no  need for laborious rack building; no chance that a component might be  improperly connected; and a dramatically lower chance of connection failure.
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. A custom-designed protective cover and dolly makes  transport easy and the suspension process fast, efficient and safe.  Vertical Transporters will be available allowing for transport of four  V25 enclosures or three S28 enclosures in either front-firing or cardioid mode.
