FRANKFURT, Germany – At Prolight & Sound 2012, HARMAN's JBL Professional is expanding its revolutionary nextgeneration
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
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 underbalcony
penetration. Larger cardioid configurations are also effective where S28 is
suspended or ground-stacked in multiple cardioid blocks, each block consisting of
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.
