Description
M&K MX-150 Mk2 THX subwoofer in excellent condition . Hasn’t been used for 10+ years so had it serviced and checked at European Electronics in Moorabin. Everything tested ok, all capacitors in great condition, all switches and control pots cleaned.
Some information found online:
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!
