The JBL Variable Line Array (VLAi) Series is a revolutionary large format loudspeaker providing high-impact sound reinforcement at throw distances beyond the reach of traditional loudspeaker designs. The modular design concept provides the system designer the ability to build large line array systems for larger venue applications or to design shorter line array systems for use as distributed clusters. JBL VLAi Series is designed specifically for permanent installation applications where even coverage, high intelligibility, and very high sound-pressure levels are required.
JBL VLAi Series includes six large format horn-loaded modules with three horizontal horn coverage patterns (30°, 60°, and 90°). This horn-loaded modular concept provides the designer additional flexibility to vary the horizontal pattern within a vertical array by incorporating different modules with wider or narrower coverage patterns while still maintaining vertical directivity.
The JBL VLAi Series uses proven JBL components with patented Differential Drive® technology. The mid and high frequency sections are horn-loaded for maximum sensitivity and optimum pattern control. The midrange section features 2169H cone midrange compression drivers with an 8 inch cone diameter and dual 3 inch voice coils. The high-frequency section features large format 2432H compression drivers with 3 inch voice coil. The low-frequency section features JBL’s 2265H-1 Differential Drive® dual voice coil dual gap 15" woofer. This woofer features neodymium magnet and ultra-robust cone for extra-long life.
Enclosures feature 16mm (5/8-inch) exterior grade 12-ply birch plywood. Grills are powder coated 14 gauge acoustically transparent perforated steel. For outdoor applications JBL offers two standard levels of weather resistance. WRC is for outdoor placement where the loudspeaker will be sheltered from direct exposure. WRX is for direct exposure or more extreme environments.
Note: In mid-2018, improvements were made to VLA, adding the letter “i” to each model to denote the improvements. The “i” versions offer the following improvements:
- A simplified, rectangular enclosure shape for easier arraying.
- Updated transducers for improved performance, improved low-frequency extension and output, higher sensitivity, greater power handling, and better heat dispersion.
- Advanced FIR filters for linear-phase filtering, improved phase response across the spectrum, and enhanced array performance.
- Sealed terminal compartment eliminates the need to custom order cable lengths.
