THX Certified Ultra Subwoofer • Dual 12" Extra-Long-Throw Woofers • Sealed Push-Pull Design • Carbon-Fiber Cones • 600 Watts RMS • 1,200 Watts Peak • 18Hz–200Hz In-Room Response
The M&K Sound X12+ Dual 12" THX Subwoofer With 1200 Watt Amp combines exceptional low-frequency output with the speed, accuracy, and control required for reference-level home theater and music systems. Two 12-inch extra-long-throw carbon-fiber woofers operate in M&K Sound’s signature push-pull configuration to reduce nonlinear distortion and produce clean, symmetrical bass.
Its high-efficiency amplifier delivers 600 watts RMS and up to 1,200 watts peak, giving the X12+ the dynamic headroom needed for demanding soundtracks and full-scale musical performances. Balanced XLR and unbalanced RCA connections, adjustable phase, selectable EQ, and flexible crossover controls make it easy to integrate into advanced stereo and surround systems.
Carbon-Fiber Woofer Cones — Rigid, lightweight carbon-fiber construction supports high excursion while maintaining precise control during demanding low-frequency passages.
Signature Push-Pull Architecture — One woofer is inverted relative to the other so their nonlinear characteristics oppose one another, producing cleaner and more symmetrical output.
Distortion Killer Shorting Rings — CNC-machined extruded-aluminum rings help stabilize the magnetic system and reduce driver distortion throughout the operating range.
Rigid Sealed Enclosure — Full 25mm MDF construction and extensive internal bracing reduce panel vibration, port noise, and unwanted cabinet coloration.
THX Certified Ultra indicates that the X12+ has been independently evaluated for reference-level performance in larger home theater environments when properly installed and calibrated.
The built-in amplifier is rated at 600 watts RMS and 1,200 watts peak. The peak rating represents the amplifier’s short-term output capability during demanding bass transients.
The push-pull arrangement places one woofer in an inverted orientation. This helps cancel nonlinear distortion generated by the drivers and produces cleaner bass at high output levels.
No. The subwoofer provides manual level, phase, crossover, bypass, EQ, and power controls. Automatic room correction can be applied through a compatible AV receiver, processor, or external calibration system.
