17. If an outside antenna or cable system is connected to the product, be sure the antenna or cable
system is grounded so as to provide some protection against voltage surges and built-up static
charges. Article 810 of the National Electrical
Code, ANSI/NFPA 70, provides information with
regard to proper grounding of the mast and supporting structure, grounding of the lead-in wire
to an antenna discharge unit, size of grounding
conductors, location of antenna discharge unit,
connection to grounding electrodes, and requirements for the grounding electrode. See Figure A
(below).
18. An outside antenna system should not be located
in the vicinity of overhead power lines or other
electric light or power circuits, or where it can
fall into such power lines or circuits. When
installing an outside antenna system, extreme
care should be taken to keep from touching such
power lines or circuits, as contact with them
might be fatal.
19. Do not overload wall outlets, extension cords, or
integral convenience receptacles, as this can
result in a risk of fire or electric shock.

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 distortion, 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 magnet motor system. An integrated stabilization ring minimizes modulation inside the
motor’s static gap flux field, which aids in
reducing distortion. A 3-inch (76mm) copper voice coil is wound on a Kapton® bobbin 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 medium-density fiberboard (MDF) walls and
extensive internal bracing to reduce cabinet-induced colorations. Rubber feet are
attached to the bottom of the cabinet for
optimal stability, accommodating installations on tile and hardwood floors. Optional
(included) spikes can be installed for placement on carpeted surfaces.
The Concerta B12 features adjustable
controls and multiple connection options
which allow you to optimize its performance 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 listening 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 loudspeaker modeling. A stereo lithography apparatus aids in achieving tight tolerances.
Adding to the proud lineage of Revel’s
Ultima and Performa Series Loudspeakers,
the Concerta B12 solidifies Revel’s reputation as the leading designer and manufacturer of high-quality, high-performance loudspeakers and subwoofers.
