The black AcousticPerformance Dual 12” Direct Radiating Subwoofer from QSC is designed for use in portable and installed sound applications and provides exceptional punch while maintaining ample extension so the musically important fundamentals are solidly and accurately reproduced. The subwoofer features dual 12” woofers reversed mounted on a V-baffle for improved thermal protection and performance. The 15mm Baltic Birch enclosure is finished in an environmentally friendly, waterborne, polymer finish rugged enough for the demands of everyday use while also being field repairable. Internal bracing is employed to eliminate acoustic losses due to panel resonance while maintaining the lightweight enclosures robustness. Ample port area allows free movement of air resulting in minimal turbulence and port distortion.  

The versatility of the subwoofer is evidenced by two pole mount options for both vertical and horizontal applications. Furthermore, when horizontal, the speaker has a shallow height, desirable for under riser installs. It includes four integrated handles and an optional caster kit for ease of transport.

The subwoofer input cup features dual NL4 connectors in a crossed configuration, where pins 2 of the input are returned to pins 1 on the thru output. This configuration allows a single NL4 cable to carry both sub and top box signals without the need of a custom turn cable.  

Presenting a clean, unobtrusive look, AcousticPerformance grilles are unadorned eliminating the need to cover-up logo treatments which can be difficult to hide or remove. The grille is also lined with acoustically transparent backing adding to the enclosure’s professional appearance. 

  • Premium-grade, long excursion, dual 12” transducers
  • Shallow horizontal profile for under riser deployments
  • Advanced voicing filter sets using QSC Intrinsic Correction, available through either Q-Sys processing or CXD amplifier platforms
  • Two threaded pole cups for both vertical and horizontal applications
  • Two NL4 connectors in crossed configuration for easy pass thru to top boxes
  • Clean industrial design with unadorned grilles compliment most decors and settings 
  • Interlocking feet and recess features allow for rigid stacking
  • 15mm Baltic birch plywood construction 
  • 16-Gauge powder coated steel grilles 
  • Four integrated handles and optional caster kit for ease of transport
