The Monolith™ 13" THX® Ultra Certified 2000 Watt Powered Subwoofer sets the standard for bass output, low distortion, and reference level bass. A newly designed 13" driver, coupled with a DSP controlled 2000 watt (RMS)/3800+ watt (peak) power amplifier, brings a new dimension in low frequency bass performance to any home theater system.


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 Ultra Certified 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.


The cabinet is made of HDF (High Density Fiberboard), not MDF, resulting in a sonically inert enclosure. Internal bracing has been strategically placed to increase overall cabinet strength and limit unwanted panel vibrations that would cause discoloration and distortion. The strong cabinet and bracing combine to ensure that you hear massive amounts of bass, not cabinet resonances.


This 13" subwoofer uses three 100mm ports, with inner and outer flares. Multiple ports are used to ensure high SPL capability at low frequencies (fb=21Hz). The dual flares help reduce turbulence and asymmetrical distortions. Additional adjustments can be made by sealing the ports with the supplied plugs. The "floating" grille is made from non‑resonant MDF to provide rigidity, while the entire structure is offset from the cabinet to maximize air flow of the woofer and ports.
