  • The T18HT subwoofer is powered by a 4000W RMS (8000W PEAK) built-in amplifier. A DSP based feature board includes the essential controls to properly integrate the subwoofer into your system.

    The MDF enclosure is heavily braced and assembled with rabbet joints for strong structural integrity. The enclosure is finished with a non-reflective and extremely durable textured material. The amplifier is mounted on the rear baffle.

    The T18HT houses three 18 inch subwoofer drivers, which are capable of moving massive amounts of air. The 1 inch surround and poly cotton semi-progressive, high excursion spider allow the cone to move more than 2 inches peak to peak. The cast aluminum frame is mounted to the extremely linear and dynamic motor system, which provides the power to drive the cone in a symmetrical motion.

  • T18HT Frequency Response

    The frequency response graph shows how the subwoofer will sound for a given input frequency or tone. Accurate reproduction of the source material is achieved with a flat frequency response as shown in the graph.


    T18HT Compression

    The compression graph indicates how the output of the subwoofer changes as the input signal increases.


    16Hz - 25Hz: 118.1 dB
    31Hz - 50Hz: 131.8 dB
    63Hz - 100Hz: 137.1 dB
    16Hz - 100Hz: 132.2 dB

    T18HT Output

    The T18HT output numbers are acquired by using the Consumer Technology Association (CTA)™ Standard, ANSI/CTA-2010-B - Standard Method of Measurement for Subwoofers, formerly known as CEA-2010.
