M&K Sound X12 Subwoofer


Introduction to the M&K Sound X12 Subwoofer

Best of 2014 Awards

While most people have never owned M&K Sound speakers, almost everyone has heard them. M&K speakers are used extensively throughout the movie industry to master, mix, and edit sound. If you have ever seen Wall-E, King Kong, Lord of the Rings trilogy, Black Hawk Down, Pirates of the Caribbean, Iron Man, or the new Star Wars trilogy, you have heard the sound of M&K. In fact, I can think of no other speaker manufacturer who has won so many Academy Awards for sound; the afore mentioned films are but a fraction of M&K's rather lengthy list of Academy Award wins and nominations. Since inventing the world's first balanced dual-drive subwoofer back in 1973 for Steely Dan's Pretzel Logic and introducing the world to the first in-home subwoofer in 1974, M&K Sound has steadily gained the respect of the professional sound and recording industry.

The innovation continued at M&K Sound, and they introduced the world's first powered subwoofer in 1977. The masterminds at M&K Sound have continued to be at the forefront of subwoofer innovation and their newest subwoofers, the "X" series, promises to best all others.

The new "X" line of M&K Sound subwoofers consists of three models: the X8, X10, and X12. When asked how the new "X" line subwoofers were different from the previous generation, Claus Glaesner, President of M&K Sound USA, replied, "These subwoofers are a major step up in every way from our previous subwoofers. The build quality, driver quality, and sound quality represent a new reference level of subwoofer that was previously not available on the market."

As their names suggest, they utilize two 8", 10", or 12" drivers, respectively. The dual driver design allows the X series M&K Sound subs to move massive amounts of air while minimizing any distortion created by the individual cones.

The X8 is pending THX certification at the time of writing this review, and the X10 is THX Select2, while the X12 is THX Ultra 2 certified. The THX Select X10 is rated with a flat anechoic response to 35 Hz, while the larger THX Ultra 2 certified X12 is rated with flat anechoic response to 20 Hz, and the in-room response significantly lower. How can it get any better than reviewing one of M&K Sound's newest flagship subwoofers? Easy, you review two!
