JBL VLA-C125S-BK Subwoofer

The JBL VLA-C125S-BK is a compact line array subwoofer engineered for integrated system performance with the VLA Compact series. Built with reinforced fiberglass and steel construction, it delivers consistent low-frequency reinforcement across mix scenarios from studio monitoring to live reinforcement setups, with tactile barrier strip connectivity and a robust mounting plate for flexible positioning and system integration.

Power & Output Specifications

This subwoofer handles 1600 W continuous pink noise (6400 W peak) over 2 hours or 800 W continuous (3200 W peak) over 100 hours, producing a maximum 127 dB SPL at 1 meter. The dual 15-inch Differential Drive® transducers with 3-inch voice coils provide the efficiency and power handling necessary for capturing and reinforcing deep low-frequency content with clarity and control in full-range recording and mixing applications.

Design & Build Quality

The enclosure combines a fiberglass shell with 18 mm birch plywood internal bracing and 14-gauge zinc-plated, powder-coated steel grilles wrapped in acoustically transparent cloth and hydrophobic mesh—engineered for consistent acoustic performance and durability across varying studio and live environments. An IP-55 rating protects against dust and moisture, while the compact 508 x 848 x 634 mm footprint and 56.7 kg weight enable efficient placement and system configuration in studios and touring rigs.
