REL S/550 - ACTIVE SUBWOOFER

A Massive Step Forward
S/550 is the gateway to the Serie S line, delivering the speed, depth, and nuance that define REL’s performance ethos. While its larger sibling, the S/850, sets the ultimate benchmark, the S/550 carries forward many of the same design innovations—ensuring the essence of Serie S is fully realized in a more compact form.
The results are remarkable: S/550 offers lightning-fast transients, deep articulate bass, and tonal balance that breathes life into both music and film. Its ability to combine authority with refinement makes it an ideal choice for those seeking a true high-end experience in medium-sized systems, with performance that consistently exceeds expectations.
For those seeking a more bespoke finish, S/550 is available with an optional Premium Wood Grille upgrade for added warmth and individuality.

Designed for Excellence
Take in the design as a whole: horizontal strakes carved into the side walls, elegant elliptical returns that cradle handles finished in a warm golden-silver, echoing raw titanium. Everywhere you look, thoughtful details emerge—but the purpose is clear. This generation delivers the seemingly impossible: a larger cabinet that is lower, wider, and deeper, yet visually lighter.
The added internal volume gives drivers greater freedom and amplifiers improved efficiency, while updated internal bracing keeps cabinet resonances firmly under control. Subtler touches also make a difference, badges that disappear into the grille cloth, silver accents that rest quietly within the cabinet plane, and model numbers etched discreetly into the front rails, visible only when stacked in a Line Array.
An optional Premium Wood Grille adds warmth and individuality, while front-rail leveling adjusters ensure effortless setup, even on uneven floors. Together, these refinements reflect REL’s philosophy that great design is as much about thoughtful usability as it is about beauty and performance.
