M&K X15+ Subwoofer
The most advanced subwoofers technologies for the future
New Carbon Fibre Woofer Cones have been developed for all models with ultra-high strength and rigidity to accommodate the added power and excursion of the new X+ Series. M&K Sound’s proprietary CNC-machined, extruded aluminium Distortion Killer Shorting Rings also guarantee absolute control and distortion-free, exemplary performance in all settings.
M&K Sound’s iconic Push-Pull subwoofer architecture and “reversed double driver” non-isobaric configuration mean that both drivers in the cabinet are ‘exposed’ to room air. Consequently, and like the X-Series before, the X+ Series models are effectively two subwoofers in one cabinet enabling a further associated reduction in distortion. This is made possible by having one inverted driver in relation to the other cancelling non-linearities to produce totally symmetric waveforms.
The X15+, X12+ and X10+ all feature full 25mm MDF construction and bracing for negligible panel vibrations or cabinet resonances, and increased venting at the base of the woofers mitigates distortion due to air turbulence. These milled cavities also act as convenient carrying handles for installation efficiency

Caring for your Speakers and Amplifiers
To Keep your equipment safe these are some best practices to note. Please be advised that this is only to reduce the risk of misuse and is not an exhaustive list.
Speakers
- Speaker terminals are marked red and black, ensure your amplifier to the speakers are wired on the same colours
- Ensure no loose speaker wire from the red touches a loose wire from the black as this will lead to a short circuit and damage either the speaker, the amplifier or both.
- Not all speakers are designed to play at max volume, kindly consider the pairing of your amplifier and speakers
- Speaker cabinets cannot be replaced please handle with care.
AV & Stereo Amplifiers
- If your amplifier has HDMI ports, ensure all devices are off before plugging in the HDMI cable
- Turn off the amplifier before swoping out or adding speaker cable
- Amplifiers generate heat, place them in a well ventilated space. if possible avoid having anything on top of the unit.
- adding a surge protector can assist with power dips which are likely to damage your devices. Isotek and Furman are industry standard.
- Dusty environments can sometimes lead to accumulation of dust in the electronic components that might affect heat regulation
