The LSR6312SP powered subwoofer is based on a 12" woofer with JBL's patented Differential Drive® and 250 Watts of power.
Features :   Specifications :
  • Multi-format powered subwoofer for Dolby Prologic, AC-3, DTS and other surround formats.
  • RMC™ Room Mode Correction provides electronic control of response peaks due to room modes. RMC Calibration Kit included.
  • 250 W continuous output power amplifier.
  • Sophisticated LCR bass management system.
  • Direct LFE input with selectable 10 dB input sensitivity.
  • Summed output allows chaining of multiple LSR6312SP for multiple subwoofer systems.
  • Differential Drive® technology with dynamic braking for extended low frequency response and low power compression.
  • High-density baffle for low resonance and stable inertial ground.
  • Linear Dynamics Aperture port design eliminates port turbulence and reduces port compression.
  • Reinforced enclosure and convenient mounting points for mounted installation.
