Monolith THX Ultra Powered Subwoofer

Available in 500 Watt & 1000 Watt

The Monolith THX subwoofer sets the standard for bass output, low distortion, and affordability. With chest thumping bass that plays down to well under 20Hz, the Monolith subwoofer unleashes cinema level volume, with the ability to convey and articulate the subtle nuances of music.

THX Select products are for medium sized rooms, up to 2,000 cubic feet in size, with a 10-12 foot viewing distance from the screen The THX Monolith Sub woofers are available with a 10,12 or 15 Inch Woofer Dual aluminum shorting rings are used to cancel eddy currents, further stabilizing the magnetic flux and significantly lowering distortion.

Features

THX Ultra

THX ensures the highest audio performance possible. Ensure the speaker can reach the high volumes necessary to achieve THX Reference Level without creating audible distortion or artifacts.

500 or 1000 Watts

The 500W RMS amplifier (900 watts peak power) is built around a Texas Instrument 48-bit data path (with 28-bit filter coefficients) and DSP engine.The 1000W RMS amplifier (1800 watts peak power) is built around a Texas Instrument 48-bit data path (with 28-bit filter coefficients) and DSP engine

10,12,or 15 Inch Woofer

The Monolith 10, 12, or 15 Inch drivers were 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 dual ports that can utilize a foam plugs to run the subwoofer in a sealed mode.

Anatomy of a Subwoofer

Cabinet and Internal Bracing

HDF (High Density Fiberboard), not MDF, was utilized resulting in a sonically inert cabinet. 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 you hear massive amounts of bass, not cabinet resonances.

Ports and Grille

The dual flares help reduce turbulence and asymmetrical distortions. Additional adjustments can be made by sealing the port with the supplied plug. 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.

Anatomy of a Subwoofer The lower and upper suspensions are designed together with the motor structure The spider is made from multiple layers of NOMEX with integrated tinsel leads hand stitched in place Developed after months of modeling and prototyping to ensure the highest levels of excursion The motor is made of CNC milled low carbon steel in the modified undercut “T” pole assembly

The lower suspension is critical for maintaining very low levels of distortion at high excursions, which are required for high SPL at low frequencies laser based optimization were utilized to create this durable, high profile surround that’s made from a unique formulation of NBR (

All Amp’d Up

Each amplifier’s transfer function, power output limiting, and thermal protection are monitored to the millisecond and are customized for each individual woofer and cabinet air volume combination. This state-of-the-art Class D amplifier technology ensures maximum headroom capability, excellent transient response, high output, and very low distortion when driving the Monolith THX Select subwoofer.

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 virtually unlimited design flexibility with the assurance of no signal degradation FEA (Finite Element Analysis) modeling and Klippel laser based optimizations were used to design a cone that is capable of astounding >78mm peak-to-peak excursions

The tests ensure the speaker can reach the high volumes necessary to achieve THX Reference Level without creating audible distortion or artifacts.
