The 400-watt Harbinger S12 compact powered subwoofer adds high-impact low end to any PA setup, letting you hear elements of your music or presentation like never before. High headroom, low distortion and a transparent, dynamic DSP limiter provide outstanding clarity and impact even when pushed to the max. The S12 includes a Time-Align Delay adjustment feature that lets you dial in the ideal alignment with your full-range speakers, resulting in maximum fidelity and low-end impact. The convenient Crossover Frequency circuit allows selection of crossover frequency based on either speaker size, or a specific frequency you choose. And with 130dB Max SPL output, the S12 delivers enough clean, deep bass to keep up with the most powerful full-range amps or speakers, whether you’re in a high-volume practice session, or performing on stage. Plus, the top pole socket makes it easy to mount a full-range speaker on top using a standard speaker pole.

  • 400-watts RMS, 1,000W peak, 130dB Max SPL
  • Dual Combo-Jack line inputs and outputs
  • Time Aligning Delay guarantees max bass response when used in any rig

  • Road-worthy plywood cabinet with rugged polyurea coating for durability
