Is this subwoofer designed for studio recording or live sound only?

This subwoofer is engineered specifically for live performance, touring, festival PA, and installed venue systems. It is not intended for home recording, bedroom setups, or studio tracking applications.

What are the power and SPL specifications?

The VLA-C125S-BK delivers 1600 W continuous pink noise (6400 W peak over 2 hours) or 800 W continuous (3200 W peak over 100 hours), with a maximum SPL of 127 dB at 1 meter. Its dual 15-inch Differential Drive transducers with 3-inch voice coils provide the efficiency and headroom needed for demanding reinforcement.

How does this subwoofer integrate with the VLA Compact line array system?

The VLA-C125S-BK is purpose-built for seamless integration into VLA Compact systems, with frequency response (52–210 Hz at −10 dB) and the included mounting bracket designed to match the line array configuration. Its compact footprint (508 x 848 x 634 mm) and 56.7 kg weight also pair well with touring transport and flexible venue rigging.

What protection does the IP-55 rating provide?

The IP-55 rating protects against dust and water jet spray, making the subwoofer suitable for outdoor festivals, wet venues, and installed systems exposed to the elements. The hydrophobic mesh grilles and powder-coated steel hardware further resist corrosion and moisture damage.
