Product Details

MK Sound S-150MKII Black Bookshelf Speaker, Model S150MKIITHXBK

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 nearly 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 is the new S-150MKII THX Ultra2.

The razor-sharp imaging of the S-150MKII THX Ultra2 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, MK 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 theater) and assists in providing a more focused and coherent sound for the listener.

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-150MKII THX Ultra2 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 MK’s Professional Monitors and designed for music and theater systems in small to large size rooms, the S-150MKII 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.
