REL Acoustics S/550 Subwoofer

10" active CarbonAlloy driver, 12" passive radiator, and 550 W class-D amplifier

The S/550 carries the DNA of the S/850 in a more compact form, engineered for medium rooms and dual-use systems. Its redesigned 10" active driver and 12" passive radiator deliver faster response, greater travel, and bass that is louder, richer, and more effortless than ever before.

A wider, lower-profile cabinet enhances scale and presence, making the S/550 feel larger than its footprint suggests. Compact in size but bold in performance, it redefines what a mid-size subwoofer can achieve.

Each unit comes finished in Piano Black or White Gloss with a matching cloth grille (black or white). For an even more refined look, a premium sculpted wood grille is available. As with all Serie S models, the S/550 is Airship Directâ„¢ ready, ensuring wireless freedom without sacrificing speed or detail.

The Upscale View

As the entry point into Serie S, the outgoing S/510 carried the speed and agility of Serie T/X, but with added bass extension. This involved the use of lighter and stiffer drivers and faster input filters, and a lot of work went into getting this elusive combination perfect. We're excited that the S/550 is even faster, lighter, and more powerful. 

What’s New in Serie S

  • Faster, lighter drivers with carbon-fibre refinements
  • Redesigned passive radiators with greater travel
  • Amplifiers with expanded headroom and control
  • Wider, lower cabinets for improved scale and presence
  • New grille options: cloth (standard) or sculpted premium wood (optional)
  • Airship Directâ„¢ wireless compatibility across the range
