Owner’s Manual

ABOUT THE F12

Thank you for purchasing the Revel
Concerta F12 Floor-Standing Loudspeaker.
A full-frequency reproducer, the F12 delivers
accurate performance with wide frequency
range, low distortion and high output
across the entire audible spectrum. F12
loudspeakers are ideally suited as main
speakers in stereo system setups or as the
front speakers in a multichannel surround
home theater installation. Four proprietary
transducers, sophisticated filter networks
and an acoustically inert cabinet allow the
F12 to achieve precise imaging and impres­sive performance befitting the most
demanding home entertainment systems.

As a three-way loudspeaker, the F12 trans­ducers effectively cover the entire audible
spectrum. Two 8-inch (203.2mm) woofers
deliver highly refined and dynamically
authoritative low frequencies down to the
lowest octaves. Housed in its own
sub-enclosure, a 5.25-inch (133.35mm)
midrange handles critical mid-band fre­quencies with natural tonal balance over a
wide dynamic range. A 1-inch (25mm)
dome tweeter reproduces high frequencies
to above audible frequencies. The tweeter
is mounted in a proprietary Controlled
Acoustic Impedance waveguide which opti­mizes the off-axis response of the system.
The result is superior coherency and musi­cal realism.

Combining superior form and function,
the F12 loudspeaker’s proprietary drivers
feature a distinctive design that allows for
smoother frequency response. The woofer,
midrange and tweeter cones are construct­ed with Organic Ceramic Composite
diaphragm material which helps to reduce
distortion. The spiders are constructed with
a high-strength Nomex/cotton blend with
optimized geometry for increased linearity.
The woofer and midrange also include
butyl rubber surrounds that provide for
large, linear excursion capabilities.

The midrange is built with a 1-inch
(25mm) voice coil with a high-temperature
bobbin that enables high-power handling.
The midrange features optimized and
shielded magnetic circuits to minimize
harmonic distortion and prevent monitor
interference.

The woofer includes a copper voice coil
wound on a 1.5-inch (38mm) Kapton®
bobbin that enables higher power
handling. The woofer is also constructed
with a vented center pole for increased
high-temperature cooling and low com­pression.

The tweeter dome is under-hung with
copper-clad aluminum wire to prevent
distortion. The tweeter’s magnet contains
Ferrofluid® which helps to achieve higher
power handling with reduced compression.
The tweeter is also magnetically shielded
to prevent video monitor interference.

High-order filters at 575Hz and 3.0kHz
optimize loudspeaker on-axis and off-axis
response, helping to ensure smooth octave­to-octave balance and timbral accuracy.
Removable shorting-straps and gold-plated
binding posts accommodate single-wired,
bi-wired and bi-amplified connections.

The F12 cabinet is constructed with medi­um-density fiberboard (MDF) walls to
reduce cabinet-induced resonances. Rubber
feet are attached to the bottom of the cabi­net to accomodate installations on tile or
hardwood floors. Optional (included) spikes
can be inserted into the feet for placement
on carpeted surfaces.

REVEL Concerta F12

Owner’s Manual

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 F12 solidifies Revel’s reputa­tion as the leading designer and manufac­turer of high-quality, high-performance loud­speakers.

and to other precautions that appear
throughout this owner’s manual.

WARNING

alone. Proper lifting requires at least
two strong adults.When lifting the F12,
stand as straight as possible using your
leg muscles to lift. Do not attempt to
lift the F12 while bending at the waist.
When moving the F12, rock it side-to­side into the desired position. Failure to
follow these procedures may result in
personal injuries and/or loudspeaker
damage.

When unpacking, save all packing materials
for possible future shipping needs. Refer to
the Obtaining Service section on page 17
for additional information.

To unpack the F12:

4. Remove the bottom pad and the
microfoam sheet. These items are
identified in Figure 3 (right).

Note

If the F12 is to be placed on a carpeted
floor, install the spikes while the loud­speaker is upside-down. Refer to the
Feet and Optional Spikes section that
begins on page 11 for instructions.

5. Grasping the sides of the cabinet, place
the F12 on its side. Then, place the F12
in the upright position.

6. When the F12 is in the upright position,
