REL Acoustics Serie S 12-Inch Powered Subwoofer in Gloss White Lacquer (Each) - S/850 WHITE

REL Acoustics S/850 WHITE Serie S 12-Inch Powered Subwoofer in Gloss White Lacquer (Each)

The REL Acoustics S/850 WHITE Serie S 12 in powered subwoofer pairs an 850-watt RMS Linear Class D amplifier with a front-firing CarbonAlloy driver and a down-firing 12 in passive radiator for two-channel music and home theater. In-room low-frequency extension is specified at -6 dB at 19 Hz, with a recommended room size of 300-700 sq. ft. Simultaneous High Level and .1/LFE operation keeps music and movie-effects signals connected in a shared system. This single-subwoofer configuration wears eight coats of Gloss White Lacquer and includes a cloth grille.

Key Features

Gloss White Lacquer and Recessed Stainless-Steel Handles

Light-catching contours, metallic badges and inset stainless-steel handles give the white cabinet its distinctive presentation. Eight coats of glossy lacquer complement the shaped enclosure, while recessed handles integrate practical handling into the design rather than interrupting its profile.

12 in CarbonAlloy Driver for Impact and Detail

A pure carbon-fiber center cap replaces the previous solid aluminum cap to reduce moving mass and increase stiffness. That material choice is intended to help the long-throw cone respond to explosive transients as well as quiet low-level passages, addressing musical detail alongside movie impact. A die cast alloy chassis supports the active driver.

Long-Travel, Down-Firing Passive Radiator

Below the cabinet, the passive radiator's carbon, glass-fiber and closed-cell-foam piston is designed to accommodate the excursion demands of the amplifier and active driver. More than 2.4 in of movement in each direction supports low-frequency output, giving the passive system an important role in reproducing deep bass passages in music and film.

850 Watts RMS, With Brief 1,000-Watt Surges

A traditional power supply supports continuous output, while brief 1,000-watt surges are specified separately from the 850-watt RMS rating. The Linear Class D architecture combines bass impact with efficient operation. Revised input filters use thin-film capacitors associated with flagship designs, with an emphasis on transparency, staging and control.

Analog Integration for Stereo and Home Theater

The speaker-level Neutrik Speakon input takes its signal from the main amplifier's speaker outputs, carrying that amplifier's sonic character as the subwoofer blends with the main speakers. This connection carries an audio signal, not the subwoofer's operating power.

For line-level connections, the rear panel provides two low-level RCA inputs plus separate LFE RCA and LFE XLR inputs. High Level and .1/LFE can remain active together, allowing stereo listening and dedicated film effects without routinely changing the operating arrangement.

Expandable Arrays With Integrated Leveling

The design supports stereo pairs and stacked arrays of up to three subwoofers per channel.¹ Supplied mounting hardware, thick internal aluminum handle reinforcements and rail-integrated leveling components support array installation. A knurled aluminum adjustment knob helps level the bottom unit on uneven or soft floors, including thick carpeting.

Optional Airship Direct Wireless Audio

When a room-spanning signal cable would be visually intrusive or impractical, Airship Direct offers an optional wireless connection.² It transmits High Level and .1/LFE signals together, with a receiver arrangement that plugs into the rear panel. Wireless applies to the audio connection: the subwoofer still needs mains power through its supplied AC power cord.
