Unveiling the Stars of Serie S >>>

212 Black Label – Scale, Power, Refinement

A powerhouse featuring dual 12″ CarbonAlloy™ active drivers, dual 12″ passive radiators, and a 1,000-watt Linear Class D amplifier. Built to anchor grand theaters or elite stereo systems, it delivers breathtaking dynamics, speed, control, and authority. A definitive statement in bass performance. (Exclusive to select Black Label dealers; optional premium wood grille available.)

Carbon Special Black Label – Carbon Power, Crafted Detail

Sonic supremacy in a mid-sized chassis. It pairs a 12″ all-carbon fibre driver (inspired by the Reference No. 31), a 900-watt amplifier, and handcrafted hardwood grilles. The outcome: power, speed, elegance and scale at the pinnacle of Serie S design.

Serie S/850 – A Template for Greatness

This is the model that shapes the entire range. With an 850-watt amplifier, 12″ CarbonAlloy™ active driver, and 12″ down-firing passive radiator, the S/850 delivers explosive attack, monumental output, and whisper-quiet refinement. Expect dynamic range, effortless depth, and tonal richness—it’s the benchmark by which all others stand. (Optional premium wood grille available.)

Serie S/550 – A Massive Step Forward

Sleek design meets seductive presence in a lower, wider package. Featuring a 550-watt Pure Class D™ amplifier driving a redesigned 10″ CarbonAlloy™ active driver, paired with a lightning-fast 12″ Carbon/Carbon passive radiator re-engineered for 50 % more excursion. Expect louder, faster, richer bass power that defies its scale. (Optional premium wood grille available.)

Why Serie S Stands Apart

REL subwoofers combine precision-engineered front-firing drivers and passive radiators for deep, musical bass that remains articulate and expressive—even in compact enclosures.
Serie S amplifies these virtues with renewed power, better control, and a refined aesthetic—making it the ideal subwoofer choice whether you’re elevating your music or home theater setup.
