M&K X12+ Dual 12″ THX Subwoofer With 1200 Watt Amp

The most advanced subwoofers technologies for the future

New Carbon Fiber 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 aluminum 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 canceling 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

M&K’s function and form coexist in harmony

Cosmetic makeovers for the X+ Series arrive in the form of recessed front baffles and convenient invisible magnetic grille attachment mechanisms. Harmonizing with the bold but Scandi-cool looks of the M&K S150 and S300 speakers, the new subwoofers offer cleaner lines and more discreet curved edges to complement living spaces or dedicated home cinema rooms

Why Your system Needs an M&K Sound X+ Series Subwoofer

Above and beyond the obvious, simplistic answer: “more and better bass”, the combination of a well designed and conscientiously constructed subwoofer and main satellite speakers offers worthwhile performance advantages that improve overall system performance in many critical areas that are equally relevant for stereo and surround, for movie viewing and music listening.

Here’s what happens when you physically separate reproduction of low frequency information from the upper and mid ranges. The most widely acknowledged benefit, of course, is improved deep bass extension, higher deep bass output levels and more control and authority, i.e., your system will play deeper, louder, cleaner, tighter bass.

With an M&K Sound X+ Series subwoofer, bass is exclusively reproduced by a speaker created and optimized for that purpose only. Removing the burden of deep bass from your main speakers provides major improvements in essential parameters such as midrange purity and accuracy. By liberating your main speakers from handling the tremendous demands of low bass, you also increase their effective power handling capabilities significantly, so that they can play louder without distortion.

Because your main amplifier no longer handles deep bass, the amount of power needed to achieve a given output level from your main speakers is greatly reduced (typically -50%). This ensures that your amp remains well within its safe operating limits with considerable overhead readily available as needed. Independent placement of subwoofer and satellites allows you to select an optimal position for each specific frequency range. The spot that delivers best bass is almost never the one that also delivers best upper/mid performance. With no bass vibrations or internal bass pressure waves in your main speaker enclosures, resonances are eliminated for cleaner, clearer mid and high frequencies.

Since they no longer have to reproduce deep bass, your main speaker cabinets can be more compact with enhanced structural integrity for natural, uncolored sound and a narrow front that eliminates baffle diffraction distortion, resulting in more open, natural, three-dimensional sound.

No matter what some manufacturers may try to tell you, according to the immutable laws of physics: Big bass requires a big box.

Independent Evaluation

THX is a set of performance standards originally developed by Lucasfilm Ltd, the movie empire of Star Wars creator George Lucas, to lay out a set of criteria to ensure that the creations of cinematic artists are reproduced exactly as intended. The THX logo immediately became recognized as a seal of approval for quality-conscious cinema-goers around the world.

In 1991, M&K SOUND became one of the first manufacturers to join George Lucas and his Lucasfilm Home THX program for domestic installations.

Today, THX is the highest independent quality standard dedicated to the accurate reproduction of audio sources in the home. THX certification attests that the component has been thoroughly evaluated by a fully independent body and found to live up to the strictest quality requirements in the audio industry.

M&K SOUND X Series subwoofers meet and exceed THX specifications to deliver music and movies with natural, effortless realism and power.
