Superior Quality. Futuristic Performance
The legendary S150 is the culmination of more than 40 years of loudspeaker design and acoustic solution for any critical audio and video recordings. What this updated version of the legendary studio monitor does in the conveyance of exactly what is there in the recorded source, no more and no less, is difficult to formulate in just a few words.

Essentially, it does pretty much nothing, except open up a wide, clean, clear window on every aspect of recorded sound, allowing you to shift your personal focus as you choose between specific details, instruments or voices, while never losing sight of the totality of the overall musical experience.

This is THE loudspeaker
The first true update to the classic M&K S150 speaker, the new Miller & Kreisel S150 redefines sound quality and performance. The S150 is still the speaker to beat when it comes to reference monitors for professional cinema sound design or stereo recording. The new Miller & Kreisel S150 builds upon that impressive legacy by updating the design with new acoustic technology refinements.

Miller & Kreisel has taken the innovative high-performance technologies from the S300 and integrated them into the new Miller & Kreisel S150. These upgrades bring the Miller & Kreisel S150 into the future and deliver new levels of sound quality to the most demanding customers in the world.

Bass Power and midrange finesse

The exclusive, custom designed MK Sound 5.25” bass/midrange drive unit represents the culmination of over three decades of intensely focused transducer design. While most loudspeaker manufacturers make specious boasts that their drivers are “heavily modified to their specifications,” the drivers used in the MK Sound 150 range are in fact designed in-house by full-time engineers that have been instrumental in the design of MK Sound transducers for more than two decades.

Because MK Sound alone dictates the specifications for our drive units down to the very last detail, based on extensive original experimentation and research, our loudspeakers are not subject to the changing whims and fads of standard off-the-shelf drive units.

MK Sound proudly works to a higher, stricter standard, implementing meaningful changes as technology advances.

The dual 5.25” 150 woofer configuration employs a pin-cushion basket design with narrow basket flange to permit close placement of two woofers on a compact baffle. Modest baffle dimensions ensure structural integrity, while eliminating destructive diffraction phenomena.

A completely open cast aluminum basket structure with four solid pillars allows unimpeded airflow on both sides of the cone and around all moving parts for immediate heat dissipation. Unlike conventional baskets designed with a plateau for spider mounting, the MK design team opted for a cup spider design, ensuring absolutely free airflow.

The development of cone and surround, crucial components with major impact on ultimate sound quality, was a collaborative effort with Peerless, leading Danish transducer specialists intimately familiar with MK Sound’s design objectives after decades as supplier and partner.

Working closely, MK Sound and the Peerless transducer team (Among the world’s foremost transducer designers, Peerless was founded in Denmark in 1926.) developed a breakthrough cone geometry, optimized to work in combination with a unique polypropylene based diaphragm material. The Polypropylene base, infused with 20% carefully selected minerals, provides a perfect balance between cone stiffness and internal damping.

The woofer’s low reflectivity cone is the result of a carefully calibrated combination of materials and geometry with a low-loss SBR rubber surround and edge resonance stabilizer.
