MK Sound S300T Tripole Surround Speaker Pair is built to perfection, delivering crystal-clear and true immersive experience in 3D universe of sound.

MK Sound S300T Tripole Surround Speaker pair; M&K Sound invented the tripole speaker configuration to do what no conventional monopole loudspeaker can. Side and/or rear mounted S300T’s enhance 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 monitor for a perfect acoustic match. Independent, isolated side chambers house two 4” drivers per side for optimal surround coverage to rival the performance of the huge array of speakers required in movie theaters.

THX Certification
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. in connection with the premiere of Star Wars Return of the Jedi in 1983 to establish 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.

Proprietary Crossover Concept
M&K Sound’s proprietary Phase-Focused crossover networks make the S300 Series ideal for both music and movies without compromise. Seamless integration of the two driver arrays is achieved with an 4th order roll-off of the mid/ bass section (24 dB per octave) as the tweeter array is controlled by a 2nd order filter (12 dB per octave). The tweeter section incorporates effective phase correcting circuitry for resonance control to minimize system impedance variation and maintain minimal phase shift across the total system bandwidth.

The transient-optimized crossovers incorporate audiophile-grade components including highpower polypropylene capacitors with thick copper wire connections and costly distortion-less air-core inductors wound from 1.2 mm high-purity copper for virtually flat frequency response with ideal phase characteristics. Based on crossover components carefully selected for extremely tight performance tolerances and high power handling, any S300 model is a fine partner for virtually any amplifier. Wide horizontal directivity provides even coverage of the listening area, while controlled vertical directivity reduces reflections off the floor, ceiling, tables, etc. By significantly reducing reflected sound, image specificity, localization and dialog intelligibility are vastly improved.

Innovative Danish Driver Design
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 drive units.

Aerodynamic air flow design is the watchword for the new generation of drive units designed and built exclusively for the Miller & Kreisel S300 Series to ensure pure, high definition sound with extraordinary speed and transient control.

S300 drivers are built to M&K Sound’s exacting specifications by Scan Speak of Denmark, with a forty-year history of ground-breaking innovation and multiple patents for breakthroughs in every aspect of driver design.

Iconic Driver Layout with Innovative Internal Bracket Mounting
The iconic front baffle layout of the famed S150 monitor with its triple-tweeter array alongside dual woofers is also an integral aspect of the design and performance of the S300.

The S300 Series introduces specially designed separate tweeter and woofer mounting brackets for exceptional mechanical isolation from the cabinet and a tight connection between the die-cast, custom made brackets and the front baffle.
All drivers are rear mounted to the brackets and the brackets are rear-mounted to the baffle for an elegant front with no unsightly screws and no reflective edges near the drivers. This effectively eliminates a major source of coloration in more conventional, less conscientiously designed loudspeakers.

Acoustic Alignment
With the mid/woofers slightly recessed in the baffle and each tweeter mounted in a carefully calculated waveguide, the acoustic centers of all drivers can be precisely aligned for ideal phase/time relationships to deliver the flawless timing that has always been a hallmark of M&K Sound..

The demanding 1.5 Khz crossover point and precise driver positioning are critical to the achievement of fast, accurate audio reproduction. Optimal performance in this area requires correct definition of the acoustic centers of the tweeters and woofers, near the voice coil/dome assembly in the tweeter and further forward, closer to the surround for the woofer.

Positioning the drivers accordingly synchronizes the sound from both drivers for enhanced timing and exceptional rendering of fine detail.

The low crossover point requirements of larger component values minimize electrical phase delay further contributing to seamless timing of the two arrays.

The dual woofers are mounted with in the baffle with no reflective edges to eliminate reflections and resonance peaks.

The drive units in each triple tweeter array are carefully measured and matched prior to mounting. Employing three tweeters allows significantly increased power handling, reducing the load on each individual driver and making it possible for the system to operate optimally at a lower crossover point and with minimal phase shift.

25 mm Soft Dome High Frequency tweeter
Even at low levels, a dome causes compression of the captive air mass within. The S300 tweeter ventilation system is designed to ensure that there is no air mass loading the dome and to achieve extended frequency response for a smooth transition to the mid/bass unit. The Miller & Kreisel aerodynamic air flow control damping system offers an effective solution.

Triple-Layer Non-Resonant Enclosures
The Miller & Kreisel 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. All six sides employ the same extremely rigid, highly damped sandwich construction. A stereo pair consists of mirror-image, dedicated left and right speakers for optimal imaging.

The Miller & Kreisel S300 Series achieves audibly superior results with thicker, denser panels utilizing constrained layer damping, i.e., laminating the exterior of the base layer (inner cabinet) with a damping layer of tar and then adding a third constraining layer (outer cabinet). The S300 constrained layer sandwich dissipates vibration by absorbing kinetic energy and converting it into low-grade frictional heat effectively and harmlessly.

The Miller & Kreisel S300T tripole surround speaker employs independent, isolated chambers for each driver. The surround features massive 6 drive units and the dual 4 inch side-mid ranges provides the unique ambience and makes the S300T a true tripole.

The acoustic characteristics of the side and front firing S300T drivers are carefully voiced to match the S300.

Employing the S300 woofer and tweeter on the front baffle, total system timbre matching and voicing closely matches the sound of the S300 front system.

The dual sets of side-firing drivers 4 inch. incorporate a small network to ensure that the side drivers closest to the front tweeter do not interfere with the dispersion of the front firing tweeter.

The angled side panels allow the side drivers to blend seamlessly with the front drivers – for the perfect combination of diffuse and focused sound character that makes M&K tripoles unique.
