The Harbinger VS12 is a compact, lightweight powered subwoofer aimed at working bands, DJs, and small venue operators who need reliable low-end reinforcement without the weight and bulk of a full-size sub. At 46 pounds with dual ergonomic handles it loads in and out without drama, and the plywood cabinet with polyurea finish holds up to regular use. The 1000W peak Class-D amplifier drives the 12" driver down to 35Hz at a maximum SPL of 130dB — more than adequate for small clubs, houses of worship, and mobile DJ setups. The onboard DSP gives you adjustable crossover frequency, time-aligning delay for phase correction, a polarity switch, and a transparent limiter, which means it integrates cleanly with most full-range speaker systems without external processing. Dual XLR combo inputs, dual XLR outputs for daisy-chaining, a built-in USB charging port, and a 35mm pole mount round out the feature set.
This unit is in excellent condition — fully functional, clean cabinet, all controls working correctly.
