T18 Powered Subwoofer
  • Power Sound Audio's flagship subwoofer is a true exhibit of American engineering and manufacturing. We took our time designing one of the best commercially available subwoofers that will fill most rooms with concussive bass.


    • Three, USA built, proprietary 18" drivers configured in a triangular array to eliminate reactive forces
    • 4000W RMS / 8000W Peak amplifier with DSP - made in USA
    • Satin black texture cabinets - made in the USA
    • 15Hz-200Hz +/-3dB (7Hz-11Hz typical in-room extension)

    CEA-2010 Ratings

    • Ultra-low bass (20-31.5 Hz): 121.7dB
    • Low bass (40-63Hz): 135.7dB
    *Subtract 9dB for an equivalent RMS 2m ground plane measurement distance.


  • Driver

    • Three Power Sound Audio proprietary 18” drivers
    • Extended and vented pole geometry
    • Vented back plate to maximize air flow
    • Extremely linear and dynamic motor system
    • Epoxy reinforced cone neck/apex joint
    • Concentric foam surround, treated for longevity
    • Highly treated, rigid paper cone body
    • Die-cast rigid aluminum frame
    • Three inch diameter, four layer copper voice coil wound on a rigid multi-layer aluminum former with Kapton heat shielding
    • Fatigue limiting designed, silver alloy lead wires
    • Single poly cotton semi-progressive, high excursion spider
    • Paper outer dust cap with acrylic coating
    • Inner Mass Loading Cap that also strengthens the cone body
    • Assembled in the USA

      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 (less than 20w typical) 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
      • 120VAC only
      • 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


      • Sealed enclosure
      • Triaxial driver array
      • Finish options: super durable, satin black textured finish
      • Precision machined CNC panels for perfect fit of all components
      • Rigid MDF baffles
      • Dimensions (D x W x H): 27.5” x 31” x 23.5” Technical Drawing
      • Weight: 170lbs (158lbs without grills)
      • Made in the USA

    • 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."
