Serie S Pinnacle Engineering

Carbon Special Black Label elevates the medium chassis to its absolute highest form. At its core lies a 12" all-carbon fibre driver closely related to our flagship No.31 Reference design, powered by a 900-watt amplifier in an expanded cabinet that allows the carbon driver to deliver unprecedented scale and authority.

Black Label models represent the most advanced expressions of Serie S, built with tighter tolerances, upgraded components, and distinctive finishes that underscore their premium positioning within the range.

Revolutionary Carbon Fibre Driver Technology

REL's development begins with the driver—the foundation of sonic character. The Carbon Special's 12" all-carbon fibre unit handles three times the peak power of its predecessor, with newly engineered suspension allowing 60mm front-to-back travel for extraordinary dynamics with complete control.

This Reference-derived driver delivers bass that's effortless, powerful, and fluid, extending lower with greater authority. Whether reproducing subtle musical textures at concert levels or explosive theatre soundtracks, this latest-generation driver transforms performance across the entire medium-chassis class.

Advanced Hybrid Amplification

The 900-watt hybrid amplifier combines rich current delivery of Class A/B monoblocks with Class D efficiency. A substantial 15-pound power transformer and extensive heatsinking form the foundation for high-current performance, sustaining 1,250-watt peaks with complete composure.

This sophisticated design delivers louder, cleaner, and more controlled bass than any previous medium-chassis REL, uniting raw power with the composure and finesse that define Black Label engineering.

Premium Design & Craftsmanship

Cabinet proportions inspired by REL's Reference line achieve natural scale and presence. Subtle black crown inlays along sidewalls and curved stainless-steel handles recessed into elliptical returns underscore its unique position. Precision knurled billet cylinders beneath each rail permit exact levelling, whilst thick internal aluminium slabs anchor handles for safe Line Array stacking.

The included premium wood grille adds warmth whilst enhancing airflow for greater dynamics—a design where beauty and performance converge seamlessly.

Line Array Excellence

REL Line Arrays produce soundstaging and dynamics rivalling the world's finest systems. Carbon Special Black Label includes precision mechanical couplers for secure multi-unit configurations, growing from stereo pairs to three units per channel for floor-to-ceiling authority.

Proven at international shows, Carbon Special Line Arrays achieve genuine state-of-the-art performance even with compact monitors in medium rooms—delivering half-million-pound system presence in modest spaces.

Professional Connectivity

REL's 100% analogue input filters achieve truly natural sound through the renowned High Level Input, connecting directly to amplifier speaker outputs without drawing power. For ultimate flexibility, AirShip Direct™ wireless capability preserves speed, transparency, and authority whilst eliminating cable constraints entirely.

Simultaneous High Level and .1/LFE operation ensures music gains natural integration whilst movies deliver full intended impact—seamless transitions without manual adjustment.
