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."

MK S300T surround Speaker reproduces a seamless 360 degree sound field, the patented Tripolar loudspeakers combine the localised sound of a conventional rear speaker combined with the open, diffused sound of a dipolar speaker.

M&K Sound invented the tripole speaker configuration to do what no conventional monopole loudspeaker can do. The installation of side and/or rear mounted S300T’s enhances the solidity and pin-point placement of rear channel events such as fly-overs, voices, effects, music etc., as well as the realism of the ambient soundfield. The S300T tripole with integral wall-mount bracket, employs the same front drivers and crossover technology as the S300, for a perfect acoustic match. Independent, isolated side chambers house two 4” drivers per side for optimal surround coverage that rivals the huge array of speakers required in movie theatres.

Independent Evaluation

Independent 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.

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.

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.
