For sale are two of the M&K MX150 subwoofers, with THX certification.
The MX150 uses two 12 inch woofers, one mounted in a sealed enclosure (read "better, tighter bass") and a second 12 inch woofer mounted below, firing into the cabinet in reverse phase to keep room radiation in phase.
I have posted a link above, that leads to a Stereohile review by Wes Phillips, where he evaluates a whole M&K surround system, including these subwoofers.

Another article found on-line describes the MX150s in comparison to inferior ported subwoofers:
The MX-150THX's Deep Bass sealed-box design produces significant deep bass output down, with an in-room response flat to frequencies well below 20 Hz. Many other THX subwoofers have vented cabinets, giving them an extremely sharp rolloff below the lower limit of their "flat" response. By reproducing bass frequencies lower than 20 Hz, the MX-150THX has a lifelike power and authority that these other subwoofers cannot match. M&K's Push-Pull Dual Driver Configuration delivers a major improvement in bass detail and articulation by virtually eliminating even-order harmonic distortion and doubling the sound power per watt of amplifier power, for 6 dB of additional output!

MX-150THX powered subwoofer
Power output: 150 watts
Amplifier distortion: less than 0.03%, 20-125Hz at full output
Noise: better than -90 dB relative to full output
Typical room response: 20-125Hz, ±3dB
Dimensions: 23" x 15.25" x 19.625" (HxWxD)
Weight: 74 lbs.

I have two of these MX150 subs, in excellent condition. One has the position of the controls switched, and the 'MK THX' badge on the grille/cover is different, but they are exactly the same otherwise. The serial numbers are 426307 and 428806 so the dates of manufacture could not have been too far apart....and they are the same model.
They are in excellent cosmetic and operational condition.

Retail for the MX150THX was $1400.00 US with a 'street price' of $1200.00 US
You can have one for $700.00 Cdn. (One sold, one left)

Payment by cash or EMail Transfer is preferred, or Bank Money Order or direct deposit. If buyer wants PayPal, buyer pays fee.


no boxes, so a local sale is preferred. If shipping is necessary, boxes and packing materials can be supplied for a nominal fee
