Thanks to community member skgarach 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) DSP engine, allowing virtually unlimited design flexibility with the assurance of no signal degradation.

Don't they have warranty of 5 years?
Yes. I've got a 6 month old one that they just replaced. They have no US product service so they never just send an amp. Whole unit replacement.

It was a nightmare getting foreign tech support to honor the warranty since I bought mine from their Amazon store.

I am not a audiophile. I have Polk lsim series (front 705 , center 706) speakers. This 15inch is too big for my setup. My receiver has two subs. Is it a good setup to buy two 10inches rather than 1 15 inch?

It depends. The 15 inch will most likely dig deeper (hz) compared to 2 10s. But if you have a wide seating area and you place the two tens optimally, you would have reduced nulls.

If you are listening to music, there are few songs that go subsonic frequency (<30hz), but if you are watching movies, you want a sub that digs deeper so you can "feel" the impact from things like explosions.

Is there a place I can find dimensions of 10 inch sub? I searched for it in the manual but no luck.

Found it: 19.7"x15"x18.9" (lxwxh)

This is a real subwoofer with great specs and a great price. If you have a medium size room, get two and you will never have to worry about upgrading again.. Don't be like me who wasted money on several subwoofers only to yearn for more skin tingling base. I finally settled on two JTR subs and I'm now done!.

I got this on last deal. Completely shocked at how massive this is. Dominates the room. Beware! You may not have any place to put this.

Yes. I have the same setup and it sounds great. My biggest concern was how they would sound with music. Movies are fairly easy but music reveals everything. They are actually pretty punchy and sound great with music.

It's always better to buy two subs then one. It's not about volume. It's about even bass distribution. My room is only 11 x14.

Do I need to check the lift gate fee box? $125 seems steep to lower a box down from a freight truck.

Been waiting for a good price to add another PB 16 Ultra, but at this price I may fight with room corrections and placement and get this instead. This is a lot of sub for the money
