Engineered to surpass the output and dynamic scale of prior reference models, the S\/850 pairs a 12-inch long-throw CarbonAlloy™ driver—featuring ultra-lightweight pure carbon-fiber dust caps—with an 850W RMS (1,000W peak) linear Class D power amplifier. The result is a fast, uncolored, and deep low-frequency extension reaching down to 19 Hz (-6 dB).\u003c\/p\u003e\n\n\u003cp\u003eDesigned for both high-end two-channel stereo systems and home theaters, the S\/850 utilizes REL’s pure analog filter circuitry. Its famous High-Level Neutrik Speakon connection captures the exact sonic signature of your main amplifier, and it can operate simultaneously with the discrete .1\/LFE channel input. Featuring thick internal aluminum bracing and billet cylinder feet, the S\/850 is fully modular and ready for REL Line Array stacking configurations (up to 6 units high).\u003c\/p\u003e\n\n\u003ch3\u003eKEY FEATURES \u0026amp; SYSTEM HIGHLIGHTS\u003c\/h3\u003e\n\n\u003cul\u003e\n\t\u003cli\u003e\n\u003cstrong\u003e12\" CarbonAlloy™ Driver with Carbon-Fiber Dust Caps:\u003c\/strong\u003e Utilizes pure carbon-fiber central caps to reduce moving mass and increase diaphragm rigidity for transient speed and low-frequency articulation.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003e850W RMS Linear Class D Monoblock Amp:\u003c\/strong\u003e Driven by a heavy-duty conventional power supply with thin-film input capacitors for 850 Watts of sustained output (1,000 Watts peak).\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eSimultaneous High-Level \u0026amp; .1\/LFE Inputs:\u003c\/strong\u003e Features REL's pure analog filter architecture allowing high-level stereo integration and discrete .1\/LFE movie soundtracks to operate concurrently without switching settings.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eSerie S Line Array Compatibility:\u003c\/strong\u003e Built with internal aluminum slabs and precision mechanical couplers to allow stacking up to 6 units high for floor-to-ceiling line array scale.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eAirship Direct™ Wireless Ready:\u003c\/strong\u003e Fully compatible with the optional Airship Direct™ transmitter for zero-compression wireless streaming of both High-Level and .1\/LFE signals simultaneously.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eRefined Aesthetic Finishes:\u003c\/strong\u003e Elongated cabinet proportions with warm silver-gold insignia, recessed handles, billet leveling cylinders, and support for an optional Premium Wood Grille.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch1\u003eSPECIFICATIONS\u003c\/h1\u003e\n\n\u003ctable style=\"width: 100%;\"\u003e\n\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eProduct Category\u003c\/td\u003e\n      \u003ctd\u003eFlagship Reference Active Subwoofer\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eActive Driver\u003c\/td\u003e\n      \u003ctd\u003e12 in.
