What power handling does the VLA-C125S-BK deliver?

The sub handles 1600 W continuous pink noise (6400 W peak over 2 hours) or 800 W continuous (3200 W peak over 100 hours), reaching a maximum 127 dB SPL at 1 meter. Dual 3-inch voice coils in each 15-inch Differential Drive transducer provide the efficiency and thermal headroom for demanding live and installed applications.

How does the VLA-C125S-BK integrate with VLA Compact line arrays?

The subwoofer is engineered specifically for the VLA Compact series and includes a bracket plate and stainless steel bolts for seamless rigging and system alignment. Its frequency response (52 Hz–210 Hz at −10 dB) fills the low end while the line array handles mids and highs.

Is this subwoofer built for outdoor and wet environments?

Yes—the enclosure features an IP-55 rating protecting against dust and water jet spray, fiberglass and steel construction with zinc-plated grilles, hydrophobic mesh, and a powder-coated finish. These materials and seals make it reliable for touring, outdoor venues, and weather-exposed installations.

What are the dimensions and weight?

The VLA-C125S-BK measures 508 x 848 x 634 mm and weighs 56.7 kg (125 lbs), making it compact and transportable for tours and venue moves while remaining rigid enough for permanent mounting.

What type of connectivity does it use?

The sub features CE-compliant barrier strip terminals that accept up to 5.2 sq mm (10 AWG) wire or 9 mm spade lugs, providing secure touring-grade connections without fragile connectors.
