Amplifier Specifications

  • Amplifier Power: 4000W RMS (continuous), 8000W Peak (dynamic)
  • Amplifier Topology: Innovative post-filter feedback class-D topology, achieves ruler-flat frequency response, low distortion and very high damping across the whole audio band
  • Uses latest generation power MOSFET transistors and highly optimized output stage for up to 95% efficiency, allowing quiet fan-less operation up to unprecedented power levels
  • Full featured protection: DC, overload, low impedances, shorts, under/over-voltage, overheating, etc.
  • Very low idle power consumption (<20W typ.), saves electricity in comparison with most pro-audio and class AB amps
  • Includes gentle soft-start and long-term power limiter to reduce the chances of  tripping breakers
  • 120 - 240V
  • Inputs: Balanced XLR input and balance XLR loop output. 
  • Two user selectable DSP programs for optimization in almost any room size
  • LED indicators for circuit protection, clipping, AC power, and signal

Dave Upton (Home Theater Forum) spent some with our flagship subwoofer, the T-18. Click the Home Theater Forum logo to read his impressions of what he calls, "the best value in high end subwoofers."

" it was obvious that the T-18 could handle ultra-pressurizing subsonic content with ease as well as deliver a huge amount of impact. Turning the volume anywhere close to reference level had my room rattling in ways I never thought possible. Even with such impressive output capacity, the T-18 was remarkably dynamic also, delivering intense bass without being rude about it."

"With the T-18 properly dialed in, the experience was the most intense home theater bass reproduction I’ve ever encountered from a non-DIY sub."
