Revel B120 User Manual

he Revel® Concerta™ B120 is a high-performance

T

powered subwoofer, designed to add essential bass
response to any music or home theater system,
particularly those built around Revel Concerta
Series loudspeakers. The B120 subwoofer
delivers accurate and authoritative bass from
a surprisingly compact enclosure. Adjustable
controls, parametric room equalization and
multiple connection options provide unequaled
placement flexibility, and allow you to optimize
low-frequency performance for any listening
environment. An optional wireless transmitter
greatly simplifies installation.

Featuring a 12" (305mm) woofer with 1-1/2"
(38mm) peak-to-peak excursion and a 250-watt
(RMS) amplifier, the B120 adds serious bass punch
with very low distortion, even at the lowest
frequencies and at high output levels. A huge
2" (51mm)-diameter copper voice coil on a

contributes to impressive power handling and
freedom from dynamic compression.

About Revel

A multichannel listening lab, facilitating •
double-blind listening tests

A laser interferometer, enabling detailed driver •
and cabinet analysis

Multiple large anechoic chambers, providing •
precise tests and measurements

Finite-element analysis, allowing for advanced •
loudspeaker modeling

Stereo lithography equipment, aiding in the •
achievement of tight tolerances

Subwoofer Specifications

Transducer

The B120’s proprietary woofer diaphragm is constructed
of micro ceramic composite (MCC), a new material
created by adonizing both sides of an aluminum
core. Anodizing both sides of an aluminum core adds
strength and stiffness – but very little weight – to a material
already well suited for use in transducer diaphragms.

The B120 spider incorporates a superior-strength

Nomex

/cotton blend with optimized geometry for

increased linearity.

The large ceramic magnet motor system includes a
2" (51mm)- diameter copper voice coil wound on a

®

Kapton

bobbin for impressive power handling and
freedom from dynamic compression. A vented center
pole facilitates heat dissipation, allowing more efficient
cooling for high-power handling and low compression.

Built-In Wireless Receiver

With an optional TX1 wireless transmitter connected to
your audio system, the B120 can be placed anywhere in
your room within reach of an AC outlet. One or two B120
subwoofers can be operated with a single TX1 transmitter.

Fully Parametric Room EQ

Any subwoofer’s performance will be, to at least some
degree, affected by the acoustics of the room in which
the subwoofer is used, and where in the room the
sub is situated. Certain low-bass frequencies may be
adversely affected by standing waves (also known as
room modes), where some frequencies are exaggerated
(peaks), while others might be diminished (dips). To
tame the subwoofer’s response in the listening room,
the B120 features a parametric room EQ function, with
controls for frequency, level and bandwidth to tune out
room-induced response anomalies.

Cabinet/Port

The B120 cabinet is constructed of rigid MDF with
extensive internal bracing to reduce cabinet-induced
colorations. A downward-firing port allows for placement
against a wall or in a cabinet. Rubber-padded feet ensure
optimal stability on any floor surface.
