The three brand new THX Certified subwoofers, the X15+, X12+ and X10+, utilise M&K Sound's signature push-pull driver configuration and build on the performance of the company's former X Series subwoofers.

Per Becher, Chief Executive Officer, M&K Sound, told StereoNET:

We carefully considered how to create successors to our market-leading X Series push-pull subwoofers. However, with increasing demand for large home theatres, it was clear that we would once again need to redefine what superb bass performance means for both home and professional environments.

According to the company, the X15+ is its first 15-inch push-pull subwoofer to be THX Certification Dominus class, whether used as a single subwoofer or as a pair.

Steven Martz, Vice President of Global Technology, THX Ltd. added:

M&K audio engineers are among the world's best, and passing THX rigorous standards for audio certification, means passing hundreds of tests. M&K can be proud of this accomplishment, and audio enthusiasts everywhere will be pleased with the extraordinary pure, powerful output of these superb subwoofers.

M&K Sound says the new range includes numerous upgrades over the original X Series, including "RMS and peak wattage power hikes to enable cleaner performance over the former X10 and X12 models, care of brand-new Danish designed and built ICE Class D power amplifiers."

Power output increases to 700W RMS / 1400W Peak (X15+), 600W RMS / 1200W Peak (X12+), and 500W RMS / 1000W Peak (X10+). The updated and redesigned woofers feature 30 per cent larger voice coils and magnets (X12+ and X10+) to facilitate the substantial power output of the new subwoofers. Additionally, "increased linear excursion ensures this available extra power handling without ever sacrificing sensitivity or succumbing to distortion."

M&K Sound's iconic Push-Pull subwoofer architecture and 'reversed double driver' non-isobaric configuration means that both drivers in the cabinet are 'exposed' to room air. Like the X-Series before it, the X+ Series models are effectively two subwoofers in one cabinet, enabling a further associated reduction in distortion. M&K says, "this is made possible by having one inverted driver in relation to the other cancelling non-linearities to produce totally symmetric waveforms."

All three new models feature 25mm MDF construction and bracing to eliminate panel vibrations or cabinet resonances. Increased venting at the base of the woofers is said to mitigate distortion due to air turbulence.

Cosmetic improvements include flush-mounted front baffles and invisible magnetic grille attachment mechanisms. The new subs offer cleaner lines and more discreet curved edges to complement living spaces or dedicated home cinema rooms.

The X+ Series will be available from January 2022. UK pricing has not yet been confirmed, but in the U.S. they will sell the X10+ for $4,499, the X12+ at $4,999, and the X15+ costs $5,999.
