REL Acoustics Serie S 10-Inch Powered Subwoofer in Gloss White Lacquer (Each) - S/550 WHITE

REL Acoustics S/550 WHITE Serie S 10-Inch Powered Subwoofer in Gloss White Lacquer (Each)

The REL Acoustics S/550 WHITE Serie S powered subwoofer combines built-in 550 watts RMS Pure Class D amplification, a 10 in front-firing CarbonAlloy driver and a 12 in down-firing passive radiator. Its in-room low-frequency extension reaches 19 Hz at -6 dB, with simultaneous High Level and .1/LFE operation for stereo listening and movie soundtracks. Intended for medium-sized rooms, this single-subwoofer configuration pairs analog filtering and second-generation PerfectFilter with an eight-coat Gloss White Lacquer finish and an included cloth grille, bringing Serie S bass performance to a shared music-and-theater system.

Key Features

Built-In Power for Medium-Room Systems

For a two-channel listening setup or a room that also serves as a home theater, amplification is already inside the cabinet rather than requiring a separate subwoofer power amplifier. The intended room range of 250-500 sq. ft. gives you a starting point for matching the subwoofer to your listening space, without promising the same output in every room.

CarbonAlloy Driver and Carbon/Carbon Passive Radiator

A long-throw active driver combines a die-cast alloy chassis, pure carbon-fiber cap and redesigned suspension. Reduced moving mass supports the attack and decay of bass notes, while the down-firing Carbon/Carbon flat-cone passive radiator uses a revised low-mass piston to support excursion, depth and dynamic output. The two-driver arrangement is designed for both musical integration and movie playback.

Analog Filtering and a 20-120 Hz Crossover

Second-generation PerfectFilter works alongside analog filters and polypropylene input-filter capacitors derived from Reference models to help match the bass with the main loudspeakers. The variable 20-120 Hz crossover lets you adjust the handoff to your speakers rather than relying on a single fixed crossover setting.

High Level and .1/LFE for Music and Movies

The High Level connection takes its signal from your amplifier's speaker outputs; it does not supply power to the main speakers. Keeping that connection active alongside a separate .1/LFE feed lets one subwoofer serve stereo listening and movie effects in the same system. High Level Neutrik Speakon, stereo low-level RCA and dedicated LFE RCA and XLR inputs provide the documented connection choices, and a nominal 10-meter Neutrik Speakon cable is supplied.

From One Subwoofer to Stereo Pairs and Line Arrays

Start with the supplied single unit, add another for a stereo pair, or build toward stacked arrays of as many as three per channel. Line Array mounting hardware is included, while the additional subwoofers are separate purchases. An integrated knurled-aluminum front-rail adjustment knob helps establish a stable bottom unit on soft or uneven floors, including thick carpeting.

Optional AirShip Direct Wireless

The separately purchased AirShip Direct system carries High Level and .1/LFE signals together, so a combined music-and-movie setup can avoid long visible signal-cable runs. Wireless capability depends on this optional accessory; a mains power connection is still required, and a power cord is included.

Eight-Coat Gloss White Lacquer

Horizontal side-wall strakes, elliptical handle recesses and restrained silver accents give the cabinet its distinctive appearance, while internal bracing supports cabinet control. The standard cloth grille is included with this White configuration. A Premium Wood Grille offers an alternative decorative treatment.¹
