The X Series subwoofer is the culmination of M&K Sound's 40 years experience in the design of superlative sub bass systems. Intended for use in the most demanding studio applications, they are equally at home wherever the finest music or home cinema is required.

The M&K Sound X Series implements aluminum AC shorting rings in the magnet system and aluminum pole spacers above the pole piece. These devices make a significant contribution to the X Series subwoofers’ ability to render extraordinary fine dynamic bass detail with high precision at all levels. Meanwhile, the drivers maintain full control and respond instantaneously to the incoming signal for unparalleled accuracy and authority in the bottom octaves.

With dual 12” drive units, the X-12 THX Dual 12" Active Subwoofer provides 226 sq. in of cone area to move and control air or 40% more surface area than the X10 and 126 percent more surface area than the X8, equivalent to a single 18” driver.

You can trust any of this series’ devices with your sound needs. The all-new X Series 8”, 10” and 12” woofers have all been tailored specifically to fulfill M&K Sound’s ambitious performance requirements. They employ open baskets for free air circulation, resulting in minimal mechanical distortion by eliminating any captive compressed air mass behind the cone. Cast baskets also offer a very rigid connection to the cabinet and improved heat dissipation from the motor system for reduced power compression.
