    THX Ultra Certified: THX engineers completed hundreds of different scientific tests to ensure the highest audio performance possible. The tests ensure the speaker can reach the high volumes necessary to achieve THX Reference Level without creating audible distortion or artifacts. THX Certified Ultra products are for large sized rooms, up to 3,000 cubic feet in size, with a 10-12 foot viewing distance from the screen. Certification pending.

    15" Woofer: The Monolith 15" driver was developed from the ground up, with a design focus on achieving output, accuracy, dynamics, and linearity, while minimizing distortion. Enclosed in a cabinet made from HDF material, massive internal bracing, and outfitted with three ports that can utilize foam plugs to run the subwoofer in a sealed mode, or tune it as you see fit.

    1000 Watt Amplifier: The 1000W RMS amplifier is built around a Texas Instrument 48-bit data path (with 28-bit filter coefficients) and DSP engine. Each amplifier's transfer function, power output limiting and thermal protection are monitored to the millisecond and are customized for each individual driver. The high efficiency Class D amplifier modules are based on a proven topology that has been continuously refined over the past 4 years. The amplifier has vast reserves of power for highly accurate, deep bass for your home theater or music system.

    BEST ANSWER: We will be adding CEA-2010 @2M burst and RMS measurements by frequency in the near future.
    Does this 15 inch subwoofer only play up to 90db before it distorts? Harmonic Distortion<1% 20-100Hz (90dB @ 1m) Does not seem to be very loud. Would think we need it to play at 105db with less than 1% distortion for a ultra THX theater.
