Next Generation Dual 12" Line Array Loudspeaker
JBL VTX A12 is a complete tour sound solution for mid- to large-size touring applications and high-end fixed installations. VTX A12 was designed from scratch to address the unique challenges of rental companies, FOH engineers and tour sound production crews. Next-generation JBL transducer technology and a high-frequency waveguide design deliver unmatched performance, sensitivity and coverage. A patented JBL rigging mechanism and redesigned suspension system streamline deployment and setup. And refinements to the physical design maximize reliability and versatility, while minimizing size and dramatically reducing weight. VTX A12 isn’t just a superior line array—it’s a completely new way to approach tour sound.
·New and improved JBL transducers for the best output per weight
·Innovative HF section integrates the phasing plug and waveguide for high sensitivity and linearity even at high output levels
·Redesigned Radiation Boundary Integrator® (RBI) for reduced horn edge diffraction, improved LF sensitivity, lower distortion, and 90-degree coverage down to 250 Hz
·Next Generation LF section, including industry-defining Differential Drive woofers, with a dual magnet, dual voice-coil design for extended linear excursion
·Best-in-class rigging for streamlined, rapid deployment
·Full-face grill for superior weatherization and refined aesthetics
·New transport cart and frame for simplified transport and setup
·Optimizations throughout the design for space efficiency and reduced weight while simultaneously improving performance
·Full integration with JBL system control and prediction software
INSIDE THE INNOVATIONS
Every component inside the VTX A12 loudspeaker was designed from scratch for linear performance, high output and consistent coverage. Together, the completely redesigned low-, mid- and high-frequency sections deliver the highest output per weight, improved low-frequency extension, and 90-degree directivity down to 250 Hz.
VTX A12’s new high-frequency (HF) section features three uniquely designed drivers that combine the HF phasing-plug and waveguide into one part, which helps provide better tolerances and increased sensitivity, while reducing distortion and overall weight.
Improving upon the patented JBL Radiation Boundary Integrator (RBI), the all-new VTX A12 RBI combines four 5.5” mid-frequency drivers into the high-frequency waveguide—providing a smooth horn surface for the high frequency section.
A lightweight 12” neodymium low frequency woofer (LF) features a 4th-generation Differential Drive design, with a new dual-voice coil, dual-magnet arrangement that increases linear excursion, power handling and sensitivity.
THE NEW LOOK OF VTX A12
VTX A12 features a new full-face grill design that reduces the number of exposed components and protects the loudspeaker from extreme weather and road conditions. The enclosed grill helps the system achieve a higher Ingress Protection rating (IP55), and can be finished in a variety of colors to suit fixed install applications. The grill is under tension, virtually eliminating noise that can emanate from the perforated grill and degrade sound quality.
VTX A12 marks a giant leap forward in how the loudspeakers are rigged and transported. To facilitate quicker deployment, array elements are stacked four per vertical transporter (VT) cart in a 10-degree collapsed position. A patented internal locking mechanism makes it easy to set arrays from 0.25 to 10 degrees using selector pins. Once the system is suspended, the mechanism automatically locks the cabinet angles at the designated positions.
With the VTX Series you are not just using a product, you are gaining access to an expert system. Tools for system design and all the components to analyze, configure, set up and control a VTX system are all part of the JBL commitment to total system integration and support. The goal is maximum efficiency and the highest possible level of performance in any venue, anywhere in the world.
