REL S/550 High-Performance Reference Subwoofer
The REL S/550 represents a new standard in compact subwoofer design, merging breathtaking power with refined musicality. Equipped with a 550-watt Next Generation 5 Class D amplifier and REL’s advanced CarbonAlloy™ driver technology, the S/550 delivers exceptional speed, depth, and articulation, making it the ideal choice for both high-end music and home theatre systems.
Despite its compact form, the S/550 commands authority with its 10-inch active CarbonAlloy™ driver and 12-inch down-firing passive radiator, producing lightning-fast transients and profoundly deep, controlled bass. The result is a seamless integration of low frequencies that breathe life and scale into any performance.
ELEGANT DESIGN & ENGINEERING
Every detail of the S/550 reflects REL’s pursuit of excellence. The sleek enclosure combines a wider, lower, and deeper cabinet design with internal bracing for improved rigidity and acoustic stability. Finely machined handles and softly brushed silver accents lend understated sophistication, while front-rail level adjusters ensure perfect placement on any surface.
For those seeking an added touch of luxury, an optional Premium Wood Grille is available, each one unique in its natural grain and finish.
VERSATILITY & APPLICATION
The S/550 is optimised for medium-sized listening rooms, capable of operating as a single subwoofer, in stereo pairs, or as part of a REL Line Array configuration for expanded soundstage depth and precision.
Its high-level Neutrik Speakon connection ensures perfect phase and dynamic coherence with main speakers, while the optional wireless AirShip II system provides a clutter-free installation without sonic compromise.
