The soundstage is massive with amazing depth and outstanding cohesion and envelopment, mixed with frighteningly fast transitional changes in volume and dynamics. It never gets tiring to listen to this system and it doesn’t take tens of thousands of pounds in amplification to get the best out of it either, with even modest AVRs able to drive this sub/sat system.

The Best Of The Best!

The Best Of The Best!

"...there's also no doubting that the performance on offer is astonishing. Music and movies are brought to life with incredible accuracy and detail, along with stunning dynamics. This is quite frankly the best sub/sat system I have ever tested. Period."

The MP300 is the on wall version of M&Ks S300 reference monitor speaker. The S300 is by far the finest loudspeaker M&K has ever made.

Building on the strengths of the studios choice, the iconic S150, the new S300 provides even greater detail and insight into music and surround soundtracks. Designed for the highest fidelity mixing and post production facilities, it is equally suited for use in state of the art home cinema applications.  

Intended for placement directly on the wall behind an acoustically transparent screen, the MP300 makes the installation of the highest quality, complete home cinemas quick and simple without the need for specialist building or cabinetry and without losing floor space to large loudspeakers.

Providing the same remarkable openness and detailed three dimensional soundstage as the in room monitor, the MP300 makes it possible to enjoy the highest fidelity music and surround sound discretely in any environment.

The remarkable efficiency of this speaker ensures incredible sound pressure levels can be achieved with no distortion without the need for esoteric power amps. The result is one of the most practical, cost effective, high performance home theatre systems available.

 The MP300 is available in satin black or white.

Leading Edge Technology

Leading Edge Technology

M&K Sound’s engineers have decades of experience in the design of individual drivers as well as complete loudspeaker systems. Because we are fully conversant in the languages of both the acoustical engineer and the audiophile music lover, M&K Sound can enter into a mutually beneficial collaboration with the world’s most acclaimed makers of driver units - Scan-Speak. Aerodynamic air flow design is the watchword for the new generation of drive units designed and built exclusively for the S300 Series to ensure pure, high definition sound with extraordinary speed and transient control.

Independant Evaluation

Independant Evaluation

The Miller & Kreisel S300 loudspeaker system has been subjected to rigorous impartial testing and certified to meet the highest industry performance standard: THX Ultra2. THX is a set of performance standards originally developed by Lucasfilm Ltd. to establish criteria to ensure that the creations of cinematic artists are reproduced exactly as intended. The THX logo immediately became recognised as a seal of approval for quality-conscious cinema-goers around the world. The S300 Series monitors meet and exceed the highest THX Ultra2 specifications, and have been chosen as their new reference loudspeaker and installed in their test facilities in California.

Unique Cabinet Design

Unique Cabinet Design

The S300 Series employs a complex, box-inside- a-box construction with a non- resonant layer of tar joining the two cabinets to provide constrained layer damping. The S300 Series cabinet construction and specially designed drive units lower the mechanical noise floor drastically, bringing music and movies to life with effortless realism, building on a rock-solid foundation.

Innovative Driver Mounting

Innovative Driver Mounting

The S300 Series introduces a specially designed tweeter array mounting flange with integrated waveguide. Rear-mounting the three tweeters to the rigid cast aluminium flange provides exceptional mechanical isolation from the cabinet. The solid steel woofer mounting bracket ensures a tightly sealed connection to the inside of the front baffle.
