Get ready to rumble.

The Harbinger VARI VS18 powered subwoofer delivers earth-shaking low frequency response for live shows and installations of any size. Its built-in 600W Class D amplifier pumps out clean power with minimal distortion, even when the bass is cranked. Dual XLR and 1/4" combo jacks connect to balanced or unbalanced systems, while an adjustable crossover, time-aligning delay and limiter provide optimized sound for your setup.

Powerful Amplifier for Floor-Rumbling Lows

The VS18's 600W Class-D amplifier delivers up to 2,400W of peak power for a maximum sound pressure level of 134dB. Onboard clip LEDs for each input and front and rear limiter LEDs protect the system from overloading, allowing you to push the VS18 to its limits without worry. Its efficient design also produces deep lows with minimal distortion for a clear, chest-thumping bass response.

Tailor the Sound to Your Setup

An adjustable crossover control lets you optimize the VS18's frequency response to work with any full-range speakers in your system. A time-aligning delay corrects for phase issues that can reduce bass output, while a transparent limiter keeps the low-end tight and prevents clipping at high volumes. Control the overall level of the VS18 independent of your main speakers for balanced low frequency in any room.

Transport With Ease

Despite its power, the VS18 is highly portable thanks to ergonomic side handles and heavy-duty locking casters. Moving from gig to gig or reconfiguring for different rooms is simple, allowing you to bring deep, rumbling bass wherever you need it.

Connect to Any Sound System

Dual XLR/1/4" combo jacks accept balanced or unbalanced signals from mixing consoles, instruments and more. Two XLR outputs allow daisy-chaining multiple VS18s for even bigger systems. With comprehensive connectivity and control, the Harbinger VARI VS18 subwoofer seamlessly integrates into new or existing sound reinforcement setups.
