Monolith by Monoprice 13" THX Certified Ultra 2000-Watt Powered Subwoofer (Open Box)

THX® Certified Ultra: 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 designed for large rooms, up to 3,000 cubic feet in size, with a 10~12 foot viewing distance from the screen.
13" Woofer: The Monolith™ 13" driver was developed from the ground up, with a design focus on achieving output, accuracy, dynamics, and linearity, while minimizing distortion. It is enclosed in a cabinet made from HDF material, with massive internal bracing, and outfitted with three ports that can use foam plugs to run the subwoofer in sealed, semi‑sealed, or ported mode, as you see fit.
2000 Watt Amplifier: The 2000‑watt (RMS) amplifier (3800+‑watt peak) 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 8 years. The amplifier has vast reserves of power for highly accurate, deep bass for your home theater or music system
