THX® Certified Ultra: Add a Tower of Bass to your home theater system! This Monolith™ THX® Certified Ultra Subwoofer sets the standard for bass output, low distortion, and affordability. With chest thumping bass that plays down to well under 16Hz, the Monolith THX® Certified Ultra Dual 15" Subwoofer unleashes cinema level volume with the ability to convey and articulate the subtle nuances of music.

Dual 15" Woofers: The Monolith™ 15" 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 an HDF cabinet with massive internal bracing. The cabinet features a large, slot‑shaped port at the bottom, which can closed using the included foam plug to run the subwoofer in full sealed mode.

2000‑Watt Amplifier: The 2000‑watt (RMS)/3600‑watt (peak) amplifier is built around a Texas Instruments™ 48‑bit data path (with 28‑bit filter coefficients) 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.
