Achingly
Beautiful
Carbon Special Black Label pulls together the
finest elements of Serie S design. Its cabinet
proportions, inspired from our Reference line,
achieve a natural sense of scale. Subtle black
crown inlays along the sidewalls and curved
stainless-steel handles recessed into elliptical
returns underscore its unique position within
the range. Beneath each rail, knurled billet
cylinders permit precise leveling, while thick
internal aluminum slabs anchor the handles for
safe stacking in Line Arrays. Each unit also
includes a premium wood grille that adds warmth
while enhancing airflow for greater dynamics. A
design where beauty and performance converge.
Driven to
Perfection
At REL, development begins with the driver, the
foundation of sonic character. For Carbon
Special Black Label, we designed a 12"
all-carbon fibre unit capable of handling three
times the peak power of its predecessor. A newly
engineered suspension allows the cone to travel
over 60mm front to back, delivering
extraordinary dynamics with complete control.
The result is bass that is effortless, powerful,
and fluid, extending lower with greater
authority. Whether reproducing the subtle
textures of music at concert levels or the
impact of modern theater soundtracks, this
latest generation driver transforms performance
across the entire medium-chassis class.
Amped Up
Carbon Special Black Label is powered by a
900-watt hybrid amplifier that combines the rich
current delivery of Class A/B monoblocks with
the efficiency of a Class D output stage. A
15-pound power transformer and extensive
heatsinking form the foundation for high-current
performance, adding to the model’s weight and
commanding authority. This design sustains peaks
of 1,250 watts with ease, delivering louder,
cleaner, and more controlled bass than any
previous medium-chassis REL. The result is an
amplifier that unites raw power with the
composure and finesse that define Black Label.

Analog
Filtered to Perfection
We choose analog because it is the only way to
achieve truly natural sound. All REL input
filters are 100% analog—among the fastest ever
offered in a subwoofer. At the core is our
renowned High Level Input, which connects
directly to the speaker outputs of your main
amplifier. This doesn’t draw power; instead, it
carries the full sonic signature of your system,
allowing REL to blend seamlessly with your
speakers—a quality reviewers have praised for
decades. For systems where High Level isn’t
possible, our low-level input uses the same
analog filter circuit, available via both RCA
and XLR connections, to deliver the speed,
naturalness, and integration REL is known for.
And in theater or dual-use systems, REL uniquely
allows High Level and .1/LFE to run together—so
music benefits from natural integration, while
movies deliver the full impact intended by the
mix.
Serie S Line
Array
REL’s Line Arrays are renowned for producing
sound staging and dynamics that rival the
world’s finest systems. Designed to grow in
pairs, a Line Array can begin with a simple
stereo pair, expand with a second, and
ultimately rise to three units per channel,
delivering floor-to-ceiling authority and scale.
Carbon Special Black Label was crafted to
support the step-by-step build of a Line Array
system. It comes supplied with precision
mechanical couplers that securely lock the top
and middle units to the anchor REL below,
ensuring stability and optimal performance.
Proven at international shows and in private
listening rooms, Carbon Special Black Label Line
Arrays achieve true state-of-the-art
performance—even when paired with stand-mounted
monitors or compact floor standers in
medium-sized rooms. Imagine the presence and
impact of a half-million-dollar system, brought
to life in a modest space.
Wired For
Sound…Wirelessly
Sometimes the best wire is no wire. Quality
cables are a given in high-end audio systems,
but there are occasions where it is impractical,
unsafe, or unsightly to drape a cable across the
room. REL delivers the ultimate solution with
Airship Direct™, our optional wireless system
that transmits wide-bandwidth, compound signals,
carrying both High Level and .1/LFE
simultaneously. Even with the immense scale and
output of Carbon Special Black Label, Airship
Direct™ preserves the speed, transparency, and
authority that define REL. It allows seamless
transitions between music and movies without
ever touching the controls, all from a single
module that plugs neatly into the rear panel and
stays invisible in your room. Simple, direct,
uncompromised: Airship Direct™.
