Key Features
THX Certified Select: 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.
16" Woofer: The Monolith 16" 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 four ports that can utilize foam plugs to run the subwoofer in a sealed mode, or tune it as you see fit.
2000 Watt Amplifier: The 2000W RMS amplifier (3800+ Watts 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
All Amp'd Up: The Monolith subwoofer amplifier has an extraordinarily high power output of 2000 watts RMS (over 3800 watts peak), which can deliver massive amounts of power when needed. Each Class D amplifier is built around a Texas Instruments 48 bit data path (with 28 bit filter coefficients) DSP engine, allowing virtually unlimited design flexibility with the assurance of no signal degradation.
Every part of this driver has been developed from the ground up and customized to deliver high output, low distortion, and accurate bass. Our unique hybrid cone combines long fiber pulp and fiberglass, taking advantage of the pulp's superior stiffness with the additional rigidity and lightweight properties of fiberglass, to deliver a driver of massive durability and excursion. The result is a cone that achieves optimal motion at all frequencies it is asked to produce and beyond.
