Dual 15" Subwoofer with Differential Drive®

The VLA-C125S uses JBL proven technology components, featuring dual 15” Differential Drive® transducers.

Enclosures feature multi-layer reinforced fiberglass and steel end-panels. Grilles are zinc plated, powder coated 14-gauge perforated steel with an acoustically transparent black grill cloth backing, a hydrophobic mesh underlayer, and a waterproof rail system.

The rigging system is inherent to the design of the system. Inter-box angles are selected when the array is assembled. Other accessories include a rigging frame, pull-back bar, and a cardioid kit.


  • Compact line array module optimized for permanent install applications
  • Advanced technology component transducers for low weight and high output
  • Outdoor IP55 rated enclosure for protection from dust and water
  • Comprehensive rigging points for creating a line array configuration
  • Fiberglass box construction and weatherized components
  • Dual 15” transducers
