Line Array LoudSpeakers
JBL VTX A8
Dual 8″ Compact Line Array Loudspeaker With 110º Dispersion
The VTX A8 is a next-generation line array element that delivers JBL Professional’s flagship VTX A Series technology in a compact solution for small to mid-size rental and installed applications. The VTX A8 was designed to solve the diverse sound reinforcement needs of production companies, rental houses, theaters, houses of worship, as well as production applications requiring front fills, side arrays or other auxiliary support for larger-scale VTX systems. Proprietary JBL woofers and our latest-generation high-frequency transducer and waveguide technology, provides unmatched performance, efficiency, and a consistent 110-degrees of horizontal coverage. The A8 combines two 8” woofers, four 3.5” midrange drivers and two 2” high-frequency drivers in a single low-profile cabinet. Proprietary double-flared low-frequency ports, precisely calculated for greater low-frequency performance extend the usable operating range down to 49Hz. The VTX A8 shares the VTX A Series’ patented rigging mechanism and suspension system for streamlined deployment, while a comprehensive suite of accessories open up a world of configuration options.
Used on its own or in conjunction with the VTX B18, A12 or A12W, the VTX A8 expands the JBL VTX A Series to offer audio professionals a complete toolset for designing optimal sound systems for any application.

Footnotes:
1: Based on speaker preset selection and cabinet orientation/configuration.
2: IEC Standard: IEC shaped noise with 6 dB crest factor based on nominal impedance and a duration of 100 hours. Continuous is defined as 2x RMS.
3: Peak, unweighted SPL, measured under half-space conditions at 1 meter using broadband pink noise with a 12 dB crest factor and specified preset.
4: For more information on how to power B28 subwoofers using I-Tech 4x3500HD amplifiers refer to the VTX B28 User Manual.
5: Nominal impedance within the stated frequency range of the product. Minimum impedance is 5.6Ω at 150 Hz.
6: Front face at 0 degrees or greater down angle to allow the cabinet to drain water. Suspension components fully weather rated for indoor or covered outdoor conditions where humidity is nominally under 50% and not local to bodies of corrosive materials. Unused speakON connectors must be sealed using silicone to protect against water and moisture.
JBL continually engages in research related to product improvement. Some materials, production methods and design refinements are introduced into existing products without notice as a routine expression of that philosophy. For this reason, any current JBL product may differ in some respect from its published description, but will always equal or exceed the original design specifications unless otherwise stated.
Stunning Looks & Functionality
