Harbinger VARI VS18 18" Powered Subwoofer - White

Low-frequency authority is foundational to any high-performance live sound system, and the Harbinger VARI VS18 powered subwoofer is built to deliver it with control and headroom. This version features a clean white finish that blends easily into modern venues, event spaces and presentation environments. Driven by 600W RMS (2,400W peak) of efficient Class-D amplification and a custom 18" high-output woofer, the VS18 produces deep, punchy bass with a maximum SPL of 134dB. Designed for professional sound reinforcement, it provides the output and precision required for large venues, mobile DJs and installed applications alike.

High-Output 18" Driver With Class-D Power

A custom 18" woofer paired with a Class-D amplifier delivers tight, controlled low end across a 35Hz–150Hz frequency range. The efficient amplification platform ensures strong transient response and consistent performance under demanding conditions, making the VS18 well suited for high-energy program material and extended use.

DSP Crossover and System Alignment

Integrated DSP provides guided crossover adjustment from 70Hz–150Hz along with a full-range output option for flexible system configuration. Additionally, a time-aligning delay function improves phase coherence with full-range PA speakers, supporting smoother integration and clearer low-frequency reproduction in complex setups.

Professional Connectivity and Protection

Dual XLR/TRS combo inputs, XLR line outputs, selectable polarity and level options (-10dBV/+4dBu) allow compatibility with a wide range of mixers and powered PA speakers. Meanwhile, a transparent DSP limiter protects the system at higher output levels, maintaining clarity while safeguarding internal components.

Road-Ready Construction

Built from rugged plywood and finished in durable Polyurea, the enclosure is engineered for repeated transport and professional use. Finished in white for a clean, professional appearance, the cabinet integrates easily into event production, houses of worship, hospitality environments and other installations where visual presentation matters. A 1.5 mm steel grille and rubber corner guards protect the driver and cabinet, while four lockable 3" casters support efficient load-in and positioning. An integrated 35 mm pole mount enables secure stacking of full-range speakers, completing the VS18's dependable low-frequency foundation for portable and installed live sound systems.
