S/850

Effortless Power, Tuned for Musical Authority
S/850 is engineered for listeners who want uncompromising performance with a refined, musical touch. Drawing on innovations from our Reference line, it pairs an 850-watt Linear Class D amplifier with advanced CarbonAlloy™ drivers to deliver explosive dynamics, clarity, and effortless scale. Equally at home in high-end music systems or immersive theaters, S/850 brings control and confidence to medium-to-large rooms.

850-watt Linear Class D Amplifier for fast, controlled power delivery
12" CarbonAlloy™ Active Driver with 12" long-stroke Passive Radiator for depth and speed
Optimized for music and theater systems in medium-to-large rooms
Designed for stereo pairs and line-array configurations
Optional premium wood grille available. Crafted from natural materials, each grille features unique grain and color variations.

Stunning Design Meets Raw Power

S/850 stands as the benchmark of the Serie S line, with its design innovations shaping and elevating its three stablemates. Every improvement is sweeping and comprehensive, ensuring the entire Serie S family benefits from the advancements pioneered in the S/850.

The results are spectacular: it delivers incredible attack and output beyond even the former Carbon Special at the very limits of performance, yet with the precision, quietness, and clarity that produce true dynamic range. Lightning-fast transients, deep effortless bass, and tonal richness combine to deliver nuance that elevates both music and theater.

Designed to be Perfect

The S/850 cabinet is longer, lower, wider, and deeper—proportions that give it a naturally dynamic presence. Subtle design details refine its look and feel: clean creases that catch the light, warm silver-gold badges with a titanium-like finish, and stainless-steel handles recessed into graceful ellipses. Beneath each front rail, precision-milled billet cylinders provide exact leveling, while thick internal aluminum slabs secure the handles for safe stacking in Line Arrays. Designed to complement modern interiors, the S/850 also offers an optional Premium Wood Grille, adding warmth and individuality.
