S 150RC – Cinema Front Stage Speaker | MK SOUND



This is THE loudspeaker that helped shape Home Theater (and music recording) into what it is today……the legendary and accredited S-150.
For the first time since its introduction over 15 years ago, the S-150 has been updated in every aspect, from driver technologies to crossover design to cabinet tuning and construction.
The result we perfected perfection, the new Miller and Kreisel S-150 THX Ultra Cinema Front Stage Speaker.
Innovative Phase-Focused Design
The razor-sharp imaging of the S-150 THX ULTRA is due in part to innovative front-baffle foam treatments, cabinet design, and in great part to the Phase-Focused™ crossover. The crossover combines three important design elements: Time Domain Analysis, Frequency Domain Analysis, and Point-in-Space Analysis (a three-dimensional analysis of the speaker’s actual response in the room). While other crossover designs consider just frequency response on one axis, M&K Sound considers response at various angles in both the vertical and horizontal planes, optimizing the speaker’s three-dimensional response. This critically tuned crossover yields a very smooth and linear response over a wide listening window (very important for home cinema) and assists in providing a more focused and coherent sound for the listener.
The perfect balance
Three high-quality 1” polymer coated silk soft-dome, ferrofluid cooled dual-magnet tweeters are aligned in a vertical array, each utilizing a unique, specially designed polymeric-damped rear cavity to further enhance its superior sound. The S-150 THX ULTRA dual high-performance 5 1/4” mineral-filled polypropylene cone, magnetically shielded, dual-magnet cast basket woofers produce powerful, richly detailed low frequencies. Based on M&K’s Professional Monitors and designed for music and cinema systems in small to large size rooms, the S-150 THX ULTRA delivers unparalleled transparency, accuracy, and dynamics while effortlessly handling voices, percussive effects, and musical instruments with life-like impact, and is timbre-matched to the MP-150 and S- 150T. Available in black satin finish with black cloth grille.

While other manufacturers were building audio dinosaurs in the form of coffin-sized boxes, M&K led the way into the future with the world’s first satellite/subwoofer system, David & Goliath in 1976. The following year, M&K Sound introduced the Volkswoofer, the world’s first subwoofer with a built-in, dedicated power amplifier. The journey began in 1973, when Walter Becker of Steely Dan commissioned M&K Sound to design a studio reference subwoofer and monitoring system for the Pretzel Logic LP mixing sessions. The result was the world’s first balanced dual-drive subwoofer and Pretzel Logic went on to become a million-selling Top Ten hit and one of Rolling Stone magazine’s 500 Greatest Albums of All Time. Today M&K Sound loudspeakers have been chosen for the development and demonstration of the groundbreaking Dolby Digital cinema and home surround format, for the first public demonstration of the high-resolution Blu-ray disc format, for sound production on Star Wars Episodes I-III and countless other award-winning music, film and TV productions. A Who’s Who of the professional audio world – film, music, mastering and broadcast studios – continue to entrust their livelihood to M&K Sound reference monitors and powered subwoofers. The industry now state that M&K Sound speakers are the best for cinema reproduction in home or commercial grade cinemas
