REL S/550 – A Subwoofer That Blends Power with Musicality
The REL S/550 isn’t just about adding bass, it’s about unlocking the emotional core of your music and movies. Redesigned from the ground up, the S/550 brings breathtaking depth, speed, and scale in a cabinet that looks as good as it sounds.
Why the REL S/550 Stands Apart
Compact Power with Refinement
Featuring a 10" carbon-fiber active driver paired with a 12" passive radiator, the S/550 delivers speed, impact, and nuance that smaller subs can’t touch. With 550 watts of Class D power, it anchors systems with authority while keeping musical detail intact.
Deeper, Faster, More Musical
The new carbon driver and re-engineered passive radiator extend bass down to 19 Hz (-6dB) while maintaining lightning-fast transient response. This means kick drums hit harder, double bass feels real, and movie soundtracks gain a physical dimension without overwhelming the room.
Designed to Disappear into the Music
The S/550’s wider, lower cabinet not only adds presence but also improves integration with speakers. Whether paired with compact monitors or full-range towers, the S/550 blends seamlessly, adding depth and scale without calling attention to itself.
Wireless Freedom, Seamless Integration
The S/550 is Airship Direct™ wireless ready, allowing clean, low-latency placement anywhere in your room. Whether wired or wireless, setup is straightforward, and REL’s proven High-Level Input ensures the sub mirrors the tonal balance of your main speakers.
