Monolith by Monoprice THX Certified Sealed 500 Watt Powered Subwoofer M10-S

THX Certified Select: THX® engineers completed hundreds of different scientific tests to ensure the highest level of audio performance. The tests ensure the speaker can reach the high volumes necessary to achieve THX Reference Level without creating audible distortion or artifacts. THX Certified 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. Two subwoofers are needed to meet THX Select certification.

10" Driver: The Monolith™ 10" Driver was developed from the ground up with a design focus on achieving output, accuracy, dynamics, and linearity, while minimizing distortion. The driver is enclosed in a cabinet made from HDF material with massive internal bracing.

500-Watt Amplifier: The 500-watt RMS amplifier 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 4 years. The amplifier has vast reserves of power for highly accurate, deep bass for your home theater or music system.

The Monolith™ THX® Certified Sealed Subwoofer series 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.

Note: The Monolith 10” THX Select does not have a huge amount of midbass output, and that is likely due to the heavier moving mass of the cone and voice coil, but that is a necessary trade-off towards achieving the superb deep bass performance that it produces for its size and price. Its midbass output is commensurate with its deep bass output, whereas most subs at this pricing will have substantially more midbass output than deep bass. Clean, deep bass is more difficult to pull off, and that is what is so impressive about these measurements.
