Soundtube PL-12 Series 12-Inch Active DSP Subwoofer

The PhaseTech PL-12 series leverages advanced DSP control and a high-excursion 12″ mica-graphite poly cone driver to deliver precise, room-shaking bass. Choose between a sealed enclosure for tight, controlled response or a ported design for extended low-end output. Both feature app-controllable level, phase, EQ, crossover, auto on/off, and user presets via the MSE Sound app.

Handcrafted in Gloss Black or Matte White, these subwoofers blend seamlessly into any décor. Robust 900 W program power, versatile I/O (LFE and stereo in/out), and selectable tuning make the PL-12 ideal for home theaters, distributed audio, and commercial installations.
