ABOUT THE C32

Thank you for purchasing the Revel Performa
C32 Center-Channel Loudspeaker. With
stunning acoustical precision, the C32
delivers exceptional freedom from coloration
and distortion across a wide dynamic
range, making it the perfect companion
for the Revel Performa F32 and M22
Loudspeakers. Four proprietary transducers,
sophisticated filter networks, and flexible
placement options allow the C32 to serve as
the center channel in the most demanding
home entertainment systems.

A critical aspect of loudspeaker design,
transducers convert electrical signals into
audible sounds, profoundly impacting
loudspeaker performance. Combining
superior form and function, the C32
transducers feature a distinctive design
that provides smoother frequency response.
The woofer and midrange cones are
constructed with Organic Ceramic
Composite material to reduce distortion,
while the spiders are constructed with a
high-strength Nomex blend with optimized
geometry for increased linearity.

A true three-way center-channel, the C32
delivers a broad range of frequencies with
striking detail. Two 5-inch (127mm)
woofers provide high excursion capabilities,
reproducing low frequencies with outstanding
dynamic range. Housed in its own separate
sub-enclosure, a 3.5-inch (89mm)
midrange handles critical mid-band
frequencies with natural tonal balance over
a wide operating range. And, a 1-inch
(25mm) titanium-dome tweeter reproduces
high frequencies well above the audible
spectrum, with wide dispersion for open,
airy treble.

Placement Compensation and High
Frequency Level controls allow the C32 to
deliver stellar center-channel performance,
even when confronted with less-than-ideal
loudspeaker placement and listening room
acoustics. The Placement Compensation

control offers three settings to accommodate
loudspeaker placement in a bookcase or
wall unit; on top of a video monitor or
above a rear projection screen; or placed
on a stand. A separate High Frequency
Level control achieves precise balancing of
high frequencies for optimal timbral balance.

An advanced woofer and midrange motor
structure includes two high-grade
Neodymium magnets placed at the center
of the motor structure, inside the voice coil,
for improved magnetic shielding. Inside
the motor, a black-plated steel shield cup
facilitates heat dissipation for higher power
handling. An integrated aluminum flux­stabilization ring minimizes modulation
inside the motor’s static gap flux field,
greatly reducing distortion. A copper ring
inside the motor’s gap reduces distortion
even further. Both rings are optimally sized
and placed to maintain constant linear
voice coil inductance with forward and
backward motions.

High-order filters at 280Hz and 2.5kHz
optimize loudspeaker on and off-axis
response, helping to ensure smooth octave­to-octave balance and timbral accuracy.
Separate woofer, midrange, and tweeter
filter boards prevent mutual interference
between filter network components,
dramatically reducing distortion over a wide
dynamic range. Removable shorting-straps
and gold-plated binding posts accommodate
single-wired, bi-wired, and vertical or
horizontal bi-amplified connections.

The C32 cabinet is constructed with 0.75­inch (19mm) thick walls and extensive
internal bracing to reduce cabinet-induced
colorations. Rounded baffle edges minimize
diffraction and optimize treble response for
even greater sound enhancement. Two
threaded inserts on the bottom of the
cabinet accommodate spike footing,
providing optimal loudspeaker stability
and positioning. A sonically optimized
grille is also included.

Since 1996, Revel has stood at the forefront
of loudspeaker design. Backed with
Harman International’s extensive research
and design facilities, the Revel Performa
Series Loudspeakers benefit from cutting­edge tools such as a multi-channel listening
lab for double-blind listening tests; a laser
interferometer for detailed driver and cabinet
analysis; real anechoic chambers for precise
tests and measurements; finite element
analysis for advanced loudspeaker modeling;
and a stereo lithography apparatus for
tight tolerances.

Adding to the proud lineage of Revel’s
Ultima and Performa Series Loudspeakers,
the C32 further solidifies Revel’s reputation
as the leading designer and manufacturer
of high-quality, high-performance
loudspeakers. Each C32 is individually
hand-tuned during manufacturing to
match the production reference standard
within a fraction of a decibel, ensuring
incomparable loudspeaker-to-loudspeaker
consistency. As a result, the C32 is the
obvious choice for unrivaled center­channel performance.

Refer to the Making Connections
section that begins on page 13 for
additional information.

LOUDSPEAKER
PLACEMENT

Loudspeaker fidelity depends on the following
three factors:

1. Loudspeaker accuracy

2. Listening room acoustics

3. Loudspeaker placement

Advanced Revel design features allow the
C32 to achieve stunning acoustical
precision with exceptional freedom from
coloration and distortion across a wide
dynamic range. As a result, experimenting
with loudspeaker placement will have the
most significant impact on the C32’s
performance.

In general, it is recommended to remove
all obstructions between the C32 and the
primary listening position. The input panel
Placement Compensation switch can be
used to optimize the C32’s performance for
the loudspeaker placement options
described in this section.

The C32 is magnetically shielded to
minimize any effect on CRT video monitors.
However, small, stray magnetic fields may
affect large CRT monitors located in close
proximity to the C32. These magnetic
fields decrease rapidly with distance, so
moving the C32 farther away from the
monitor will reduce interference. It is
important to confirm that the C32 is
suitable for use with the intended CRT
monitor.

Note

DLP, LCoS and Plasma display devices are
not affected by magnetic fields.

FLUSH MOUNTED

Set the Placement Compensation switch to
Flush Mounted if the C32 loudspeaker is
placed in a bookcase or wall unit as shown
in Figure 5 on the next page (top).

11

ON TOP OF MONITOR

Set the Placement Compensation switch to
On Top of Monitor if the C32 loudspeaker
is placed on top of a video monitor as
shown in Figure 6 in the previous column
(middle) or a shelf.

If desired, spike footing can be added to
the bottom of the cabinet to create the
proper tilt angle. Refer to the Adjustable
Spike Footing section that begins on the
next page for additional information.

STAND MOUNTED

Set the Placement Compensation switch to
Stand Mounted if the C32 loudspeaker is
placed on a stand as shown in Figure 7 in
the previous column (bottom). An optional
pedestal stand is available at authorized
Revel dealers.

CAUTION

Loudspeakers placed on stands or on
top of video monitors may fall if tipped
or improperly positioned.To avoid this,
anchor the loudspeaker and stand using
the same procedures and hardware used
to anchor bookcases, wall units, and
other furniture. Harman Specialty
Group assumes no responsibility for
proper selection and installation of
hardware or for any personal injuries or
product damages resulting from improper
installation or a fallen loudspeaker.

Adjustable Spike Footing

When the C32 is shipped, spike footing is
attached to the left pad identified in Figure
2 on the bottom of page 6. For optimal
sound quality, these spikes can be positioned
in the threaded inserts on the bottom of
the cabinet.

Both 1.5-inch (38mm) and 2.25-inch
(57mm) adjustable spikes are included,
allowing for achievement of the proper tilt
angle when the C32 is placed on top of a
video monitor as shown in Figure 6 on the
previous page (middle) or a shelf. For best
results, the C32 should be tilted so the
front of the speaker is facing directly
toward the listener’s head.

To position the spike footing:

1. Place the C32 on its side on a soft towel
or carpeted floor.

2. Select the appropriate set of spikes to
create a tilt angle that aligns the tweeter
with the listener’s head.

• Select the 1.5-inch spikes for a

slight downward tilt as shown on
the left side of Figure 8 (above).

• Select the 2.25-inch spikes for a

greater tilt as shown on the right

a level balance.

MAKING CONNECTIONS

The C32 features gold-plated binding posts
and shorting-straps that allow it to be
configured for single-wired, bi-wired, or
bi-amplified connections.

CAUTION

• Never make or break connections
unless all system components are
powered off.

• Remove the input panel shorting-straps
identified in Figure 4 (page 9) before
making bi-wired or bi-amplified
connections. Failure to do so may cause
damage to some power amplifiers.

Before making connections, note the
following:

• Use high-quality loudspeaker cable
with a maximum total loop resistance
of 0.07Ω or less (for each wire run).
Refer to the table below to determine
the appropriate maximum wire gauge.

Making Connections (continued)

• Vertical bi-amplified connections must
be made with identical power
amplifiers. Horizontal bi-amplified
connections can be made with identical
or non-identical power amplifiers with
identical “gain factors.”

• When making bi-amplified connections,
both power amplifiers must receive
identical input signals from the
associated pre-amplifier. A “Y” adaptor
is required if the associated pre-amplifier
does not offer two connectors per output
channel.

• If desired, contact an authorized Revel
dealer for information about the
suitability of power amplifier
components before connecting the C32
to the associated power amplifier.

• Review the owner’s manuals for
associated audio components to
determine their connection procedures.

• Connect one pair of loudspeaker wires
to the desired C32 input connectors.
Then, connect the same pair of
loudspeaker wires to the desired power
amplifier output channel.

BI-WIRED CONNECTIONS

Bi-wired connections are made between
both pairs of C32 input connectors and
one power amplifier output channel as
shown in Figure 11 at the top of the next
page.

To make bi-wired connections:

1. Remove the input panel shorting-straps
identified in Figure 4 (page 9).

Vertical bi-amplified connections are made
between both pairs of C32 input connectors
and two separate power amplifier output
channels. These output channels can be on
one or two power amplifiers. However, if
two power amplifiers are used, these power

amplifiers must be identical. Vertical bi­amplified connections are shown in Figure
12 (below.

Note

When making vertical bi-amplified
connections, both power amplifiers must
receive identical input signals from the
associated pre-amplifier. A “Y” adaptor is
required if the associated pre-amplifier

Note

Vertical bi-amplified connections must be
made using two separate output channels
on one power amplifier or separate output
channels on two identical power amplifiers.

HORIZONTAL BI-AMPLIFIED
CONNECTIONS

Horizontal bi-amplified connections are
made between both pairs of C32 input
connectors and two separate output
channels on two separate power amplifiers.
The C32 input connectors labeled High
Frequency are connected to one power
amplifier, while the C32 input connectors
labeled Low Frequency are connected to
another power amplifier.

These power amplifiers can be identical or
non-identical, but must have identical
“gain factors.” If the gain factors are not
identical, a means of adjusting the input
level of at least one power amplifier is
required. Horizontal bi-amplified connections

are shown in Figure 13 at the top of the
next page.

Note

When making horizontal bi-amplified
connections, both power amplifiers must
receive identical input signals from the
associated pre-amplifier. A “Y” adaptor is
required if the associated pre-amplifier
does not offer two connectors per output
channel.

To make horizontal bi-amplified
connections:

1. Remove the input panel shorting-straps
identified in Figure 4 (page 9).

2. Connect one pair of loudspeaker wires
to the C32 input connectors labeled
High Frequency. Then, connect the
same pair of loudspeaker wires to the
desired power amplifier output channel.

3. Connect another pair of loudspeaker
wires to the C32 input connectors
labeled Low Frequency. Then, connect
the same pair of loudspeaker wires to
the desired output channel on another
power amplifier.

Note

Horizontal bi-amplified connections can
be made using identical or non-identical
power amplifiers. However, these power

OPTIMIZING
PERFORMANCE

To optimize the C32 for best performance:

1. When the C32 is connected, set the
High Frequency Level identified in
Figure 3 (page 7) control to 0. (Different
listening rooms may require other High
Frequency Level control settings.)

2. Set the associated multi-channel
controller or receiver for an 80Hz
crossover (or higher), even if the
loudspeaker setup does not include a
subwoofer. In its absence, the associated

Optimizing Performance (continued)

• The C32 must be used with at least
an 80Hz crossover.

• Selecting the appropriate crossover
based on accurate in-room response
measurements will result in decreased
distortion, accurate timber, and
increased dynamic capabilities.

• Contact an authorized Revel dealer
for assistance setting the associated
multi-channel controller or receiver
for the appropriate crossover.

3. Set the Placement Compensation
control identified in Figure 3 (page 7)
to correspond with the C32’s placement.

• Select the Flush Mounted setting if

the C32 is placed in a bookcase or
wall unit.

• Select the On Top of Monitor

setting if the C32 is placed on top
of a video monitor or mounted on
a shelf.

• Select the Stand Mounted setting if

the C32 is placed on a stand (such
as the optional pedestal stand).

4. Begin playback of a familiar multi­channel music or film source. Make
sure to set the associated multi-channel
controller or receiver to a mode that
uses the center channel.

• It is recommended to listen to well-

recorded dialogue from more than
one film source, as sound quality
varies from film to film.

5. Listen from the primary listening
position, increasing volume to a
comfortable level.

6. Experiment with the Placement
Compensation control setting to
compensate for effect of loudspeaker
placement on the C32’s timbre and
overall balance.

Note

Rotating the Placement Compensation
control counterclockwise increases low­frequency output.

7. If desired, experiment with the High
Frequency Level control to change
high-frequency balance and timbre.

LOUDSPEAKER VOLUME LEVELS

High-order filters include steep cut-offs to
reduce potential damage from “out-of-band”
frequencies. Combined with carefully
selected transducers and filter network
components, this approach helps the C32
to maintain its performance under
extreme operating conditions.

However, all loudspeakers have limits
when it comes to continuous playback. To
extend these limits, avoid playback at
volume levels that distort or strain sound.

CAUTION

To avoid damage, reduce volume level
immediately if loudspeaker sound is not
clean and clear.

Note

• Refer to step 2 on the previous page for
information about C32 crossover
requirements.

• If desired, contact an authorized Revel
dealer for information about the suitability
of power amplifier components before
connecting the C32 to the associated
power amplifier.

SPECIFICATIONS

Sensitivity

Impedance

86.5dB SPL with

2.83Vrms @ 1m

(4 pi anechoic)

5.8Ω (nominal)

3.3Ω (minimum @ 80Hz)

Indicates the amount of power the associated power amplifier
must deliver to drive the loudspeaker at reasonable volume
levels. Conservatively-rated specifications indicate moderate
sensitivity, meaning that a massive power amplifier is not
required to drive Revel loudspeakers to reasonable volume
levels in large listening spaces.

Indicates whether the loudspeaker presents a “difficult” or
“easy” load on the associated power amplifier. Combined
with moderate phase angles, a minimal impedance
specification of 3.7Ω allows a reasonably designed power
amplifier to drive Revel loudspeakers.

In-Room Response

±1.0dB

from 80Hz to 16kHz

Indicates sound quality in context with other specifications.
An advanced measurement, this specification closely correlates
to sound quality in a single curve – a long-standing goal of
loudspeaker engineers. Research and observation reveals
that “on-axis” response curves cannot distinguish between
two loudspeakers with radically different sound qualities.

Target Response

±0.75dB

from 90Hz to 18kHz

Indicates sound quality in context with the individual
loudspeaker’s application, considering the acoustical impact
of its placement. An ideal response goal, a target response
is not flat at either end of the audible spectrum and is used
when the ideal reference is not a flat line.

First Reflections
Response

±1.0dB

from 75Hz to 15kHz

Indicates the response listeners hear in relation to the first
reflections from walls, ceilings, and floors. This specification
indicates that Revel loudspeakers will remain accurate,
even in listening rooms that cast strong reflections.

Listening Window
Response

1.5dB

from 85Hz to 15kHz

Indicates the on-axis response of the loudspeaker. An
improved “on-axis” measurement, this specification
reduces the visual confusion of inaudible interference. It
retains full accuracy without using “spectral smoothing,”
which results in significant data loss.

Low-Frequency
Extension

Specifications are subject to change without notice.

-10dB @ 38Hz

-6dB @ 51Hz

-3dB @ 63Hz

Indicates the low-frequency response of the loudspeaker.
Studies have shown that the –10dB specification best
correlates to controlled listening tests. At low frequencies,
most loudspeaker and listening room combinations
demonstrate significant “ room gain,” which produces an
increase in levels as frequencies decrease. Unlike the –3dB
specification, the –10dB specification reflects the steepness
of low-frequency roll-offs.

Filter Network

Three-way, high-order

@ 300Hz and 2.7kHz

Indicates the acoustical characteristics of the filter network.
Steep filters indicate an optimized filter network that
produces minimal acoustical interference, low distortion,
and expansive dynamic range. Revel’s filter networks
feature carefully selected components. Woofer, midrange,
and tweeter filter boards are independent of one another.
Each includes provisions for single-wired, bi-wired, and
bi-amplified connections as well as flexible controls for
user adjustments.
