Thanks to Deal Hunter TattyBear for finding this deal.

About this item:
  • THX Certified Ultra: 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.
  • 15" Woofer: The Monolith 15" 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 three ports that can utilize foam plugs to run the subwoofer in a sealed mode.
  • 1000 Watt Amplifier: The 1000W 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 6 years. The amplifier has vast reserves of power for highly
  • 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.
  • All Amp'd Up: The Monolith subwoofer amplifier has an extraordinarily high power output of 1000 watts RMS (1800 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) DS

Yep, saw this earlier and bought 2 today. The "Open Box" are slightly cheaper, but you have to pay shipping.

any word on amp failures in these things?

I own two lower end svs subs, and they both died on me after 5 years.

I had my amp die on this within a year. Monoprice was great and shipped out a new amp, I put it in and no problems since. It has been over a year since it was replaced

Any thoughts or opinions on this verses the Klipsch RP 16? I have the RP 15 got it for $399. Love it! But the RP 16 is a big jump up in price- this is a little more doable.

I have been running my two 10" monoliths daily for the last couple years and they are still going strong. I know some have had some issues, but mine have been good.

I went from 2 SVS PB2000 to 1 of these M15. I've had it for maybe 4 years and no issues whatsoever. Big upgrade!

How did one M15 compare to 2xPB2000? I've got one PB2000 Pro already, but I wouldn't mind more oomph for movies.

Own the 10" 400w version v2 for over 2 years. Still rocksolid. Also have a svs s2000 pro. It goes head to head with it but ofcourse with more output from the monolith since the s2000 is a sealed sub.

I've got two 12" for the theater (one from 2018 and another from 2020) and a 10" for the living room that I got in 2019. They've been great!
