Frameless Architectural speakers.

The M&K Sound Frameless Architectural in-wall loudspeaker range consists of open baffle designs as well as sealed box versions of the brand’s popular satellite and on-wall models to provide wide flexibility in terms of applications and acoustic preferences. The series maintains the sonic integrity that has made M&K Sound a legend for over four decades.Unlike other in-wall makers, M&K Sound employs the exact same drivers and crossover technologies found in our acclaimed professional and consumer reference monitors to deliver consistent sound coverage throughout the room for superior imaging in stereo and surround, even when the speakers are fitted in the ceiling. M&K Sound drive units represent the culmination of decades of intensely focused transducer innovation. Timbre MatchingThe ambitious goal of the latest M&K Sound Architectural in-wall range has been to counterbalance the inevitable acoustic consequences of reducing internal volume to 20 – 30% of a normal cabinet, while preserving the celebrated neutrality, realism and musicality that are the signature of M&K Sound. This level of tonal consistency and timbre matching offers unique flexibility and the opportunity to mix and match speakers from across the entire M&K Sound line-up.

Architectural frameless

Grilles M&K’s Architectural frameless, low profile, metal mesh front grilles are a subtly elegant virtually invisible element in any living space that can be painted to match the surrounding wall. For vibration-free mounting, the M&K in-wall grilles are fitted with multiple rubber-coated neodymium magnets with more than enough strength for safe in-ceiling use. Hardened Steel Baffles The specially modified M&K drive units are mounted in solid steel font baffles to reinforce the wall and eliminate the rattle and buzz of common plastic frame in-wall speakers. The heat hardened steel is powder coated for effective rust-proofing to last a lifetime. IW 950, IW150II, IW 300 and IW28S incorporate folded baffle edges for enhanced stability in unpredictable environment.


M&K Sealed In-Wall Boxes

The materials, acoustic properties, assembly and volume of every M&K Sound sealed box are all known factors during system design, so that the construction of the wall, the type of materials inside the wall and the volume of air behind the speaker all have no impact on final performance. It is this extreme level of control over the interaction of speaker and wall that makes it possible for M&K Sound to offer designer-friendly, invisible installation at no sacrifice in ultimate musicality.

M&K Sound back boxes of 18mm MDF are painted with black structure polyurethane lacquer for moisture resistant sealed surfaces. The sealed box also provides effective protection against dust, insects and vermin. Damping pads on the rear panel eliminate vibration when in direct contact with the wall in shallow installations. All mounting hardware is pre-fitted to the box, including metal clamps to fix speaker wire in the pre-cut cable groove on the rear of the box. Gold-plated push-on terminals with +/- polarity markings allow easy cable connection without the use of tools. Torx mounting screws with special washers are used for smooth mounting along with a practical, efficient, self-tightening dog ear clamp system for a perfect seal between baffle and wall.
