REVEL Concerta B12
Owner’s Manual
ABOUT THE B12
Thank you for purchasing the Revel
Concerta B12 Subwoofer. The B12 is a
high-performance powered subwoofer that
produces prodigious low-frequency output.
The B12 perfectly augments the Revel
Concerta Series loudspeakers in stereo music
or home theater entertainment systems.
The B12 subwoofer system features a
10-inch (254mm) woofer powered by a
650-watt amplifier. The B12 subwoofer
reproduces deep, realistic bass sounds
down to the lowest frequencies with low
distortion. The B12 woofer produces up to
2-inch (50.8mm) peak-to-peak excursion
providing extraordinarily high output
down to the lowest frequencies.
Combining superior form and function,
the B12’s proprietary woofer features a
distinctive design that allows for low distor-
tion, even at high output levels. The
woofer is constructed with an anodized
aluminum diaphragm for high strength at
high output levels. The spider is constructed
with a high-strength Nomex blend with
optimized geometry for increased linearity.
The subwoofer’s motor structure features a
Symmetrical Field Gap (SFG) configuration.
The motor includes a large ceramic mag-
net motor system. An integrated stabiliza-
tion ring minimizes modulation inside the
motor’s static gap flux field, which aids in
reducing distortion. A 3-inch (76mm) cop-
per voice coil is wound on a Kapton® bob-
bin for impressive power handling and
freedom from compression. A vented center
pole facilitates heat dissipation which
allows for high power handling and low
compression.
The B12 cabinet is constructed with medi-
um-density fiberboard (MDF) walls and
extensive internal bracing to reduce cabi-
net-induced colorations. Rubber feet are
attached to the bottom of the cabinet for
optimal stability, accommodating installa-
tions on tile and hardwood floors. Optional
(included) spikes can be installed for place-
ment on carpeted surfaces.
The Concerta B12 features adjustable
controls and multiple connection options
which allow you to optimize its perform-
ance in any system and listening room.
Since 1996, Revel has stood at the forefront
of loudspeaker design. Backed by Harman
International’s extensive research and
design facilities, the Revel Concerta Series
Loudspeakers benefit from cutting-edge
development tools. A multi-channel listen-
ing lab allows for double-blind listening
tests. A laser interferometer enables
detailed driver and cabinet analysis.
Multiple large anechoic chambers provide
for precise tests and measurements. Finite
element analysis allows for advanced loud-
speaker modeling. A stereo lithography appa-
ratus aids in achieving tight tolerances.
Adding to the proud lineage of Revel’s
Ultima and Performa Series Loudspeakers,
the Concerta B12 solidifies Revel’s reputa-
tion as the leading designer and manufac-
turer of high-quality, high-performance loud-
speakers and subwoofers.
