Monoprice Monolith M15-S 15" THX Certified 1000-Watt Powered Subwoofer

THX Certified Ultra: THX® engineers completed hundreds of different scientific tests to ensure the highest level of audio performance. 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 viewing distance of 12 feet or greater from the screen.

15" Driver: The Monolith™ 15" Driver was developed from the ground up with a design focus on achieving output, accuracy, dynamics, and linearity, while minimizing distortion. The driver is enclosed in a cabinet made from HDF material with massive internal bracing.

1000-Watt Amplifier: The 1000-watt RMS amplifier is built around a Texas Instruments™ 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.
