REL S/850 Subwoofer

Experience Reference Performance from a Medium Footprint: British-Made REL S/850 Subwoofer Provides Deep Extension, Uncommon Delicacy, Cheetah-Like Speed, and Visceral Attack

Massive power output, cutting-edge driver technology, and the inclusion of all-analog filters: There's nothing average about the REL S/850 subwoofer, a design that takes the company's medium-sized chassis to reference-level peaks. Able to handle music and movies with ravishing results, the 93.5-pound unit boasts a 12-inch CarbonAlloy active driver with 12-inch long-stroke passive radiator along with an 850-watt linear Class D amplifier. Optional AirShip Direct wireless capability plus the option to stack with other S/850s in a Line Array take this sub to a sonic zenith that will transform everything you hear.

Offering terrifically deep extension and uncommon delicacy, S/850 possesses cheetah-like speed, visceral attack, tremendous slam, massive scale, and pinpoint refinement. A seamless match for medium- to large-sized systems, the British-made marvel works miracles on difficult-to-render musical instruments and low-end passages, ultimately giving works a harmonic complement even many reference-grade standalone speakers cannot provide. You'll also experience wider and deeper soundstages, broader spaciousness, improved imaging, and greater dynamics.

The wholesale updates of S/850 compared to its celebrated S/812 predecessor extend to lightweight pure carbon-fiber center caps that reduce moving mass while stiffening the cone, resulting in explosive dynamics and the capacity to resolve the quietest passages. Feather-light yet rigid, they extend performance at both extremes. Another benefit? Enhanced input filters, now equipped with the same thin-film capacitors used in REL's flagship designs, which introduce a new level of transparency and refinement unheard of in this price class. REL's signature High Level Input, which connects directly to the speaker outputs of your main amplifier, sits at the core of the design.

Befitting its championship aural character, the 16.125 x 19.25 x 21.25-inch (HWD) S/850 looks the part with no less than eight coats of piano lacquer for aesthetics that have no rival in the industry. Subtle design details further 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. A host of well-arranged connections and easy-to-dial-in settings on the rear panel make setup and tuning a breeze. A six-foot power cable, 32-foot Neutron speaker cable, and cloth grille also come standard.
