They play louder. They go deeper. They hit faster. They hit harder. Experience the New Serie S. You’re going to be blown away.
Sound That Commands Space
The new Serie S is a complete reinvention of one of REL’s most iconic lines. Cabinets are now wider and lower on select models, for greater presence. Drivers have been re-engineered for speed, control, and deeper reach. Amplifiers deliver vast reserves of effortless power.
The result is bass that digs deeper, starts and stops faster, and integrates more seamlessly than ever before.
Serie S offers not just output, but nuance, scale, and performance that transform both music and home theatre. And with the introduction of new grille options and the ability to go wireless with Airship Direct™, Serie S elevates design as much as sound.

S/850
A Template for Greatness
The S/850 is the foundation of Serie S, the model upon which the entire range was built. Every design lesson proven here shaped the rest of the line. With immense reserves of power and speed, the S/850 delivers explosive attack, immense output, and the refinement to disappear into the music or film.
Its redesigned, wider lower cabinet enhances scale and presence, while subtle details ensure it looks as refined as it sounds. Available with standard cloth grilles or the option to upgrade to premium wood, the S/850 sets the benchmark for design and performance.
Tailored For:
- Dual-use systems (music + theatre)
- Medium-to-large rooms
- Stereo Pairs & Line Arrays
Finish: Piano Black | White Gloss
S/550
A Massive Step Forward
The S/550 carries the DNA of the S/850 in a more compact form. Its re-engineered driver and passive radiator travel further, react faster, and deliver bass that feels louder, richer, and more effortless than ever before. Its new, wider lower cabinet enhances scale and presence, making it feel larger than its size suggests.
Each S/550 is delivered with a matched cloth grille (black or white), with the option to upgrade to the new premium wood grille for a refined visual finish. Small in footprint, but bold in performance, the S/550 is compact authority redefined.
Tailored For:
- Dual-use systems (music + theatre)
- Medium rooms
- Stereo Pairs & Line Arrays
Finish: Piano Black | White Gloss
