Easy to transport

Powered subwoofers are usually the heaviest piece of gear that a DJ or band will have to transport to a gig. That’s why Harbinger added smooth-rolling, locking casters to the VARI 2318S. Moving this active sub around couldn’t be easier. For added convenience, there are also ergonomic carry handles on each side of the subwoofer. Now your bandmates won’t mysteriously disappear when it’s time to load out after a show.

Stereo signal management

With dual XLR combo connections, the VARI 2318S accepts both balanced and unbalanced XLR inputs, as well as 1/4" jacks. Stereo XLR throughputs let you connect the subwoofer with a set of VARI Series or other powered speakers. Selectable crossover frequency and a phase switch put you in control of output and matching the sub perfectly with external speakers. An output level control lets you dial in the perfect amount of bass without affecting output to the connected mains.
