®
bobbins for outstanding dynamic capability and
freedom from compression.
• Ceramic-composite cones feature an optimum combination
of stiffness and low mass for low coloration and distortion, and
fully-pistonic operation throughout their entire operating range.
• Massive motor system and specially vented spiders for
high-power handling and low dynamic compression.
• Die-cast basket to eliminate coloration from resonances.
MIDRANGE
The 4-inch (102 mm) midrange features:
• 1-inch (25 mm) diameter voice coil on a glass-reinforced
Kapton

PLACEMENT
Sound quality is heavily dependent on the accuracy of all your
loudspeakers, their placement in the listening room, and the
acoustics of the room itself. Since the REVEL PERFORMA C50
center-channel loudspeaker is extremely accurate, experiment with
the following loudspeaker systems and placements (Figures 10
through 12) to enhance performance.
NOTE: The REVEL PERFORMA C50 center-channel loudspeaker
includes a user-adjustable placement compensation circuit that tailors the
response for a desired application (e.g., stand mounting, flush mounting,
or on top of monitor). See “System Optimization” on page 15 for
detailed use on the PLACEMENT COMPENSATION control.

NOTE: “Loop resistance” is the
DC resistance measured at one
end of a loudspeaker cable, with
the other ends shorted together.
CONNECTIONS
For best results, please read the following points before connecting
the REVEL PERFORMA C50 loudspeakers:
• Use high-quality speaker cable with a maximum total loop resistance (for each wire run) of 0.07 ohms or less. Use the chart in
Figure 13 below to determine the maximum wire gauge.
A high loop resistance will result in mis-termination of the
filter networks, and serious degradation of sound quality.
Use high-quality connectors on the loudspeaker cables.
Consult your Revel dealer as to specific recommendations for
your application.
• Turn off all audio system power before making any connections.
• Read the owner’s manuals that were included with your audio
components to confirm their connection procedures.
• Verify correct polarities (i.e., + to + and - to -) when making
connections, as shown in Figure 14 on the next page. Failure to
do so will cause poor imaging and diminished bass response.

SYSTEM OPTIMIZATION
(Continued)
2. The REVEL PERFORMA C50 center-channel loudspeaker
must be used with an 80 Hz crossover as follows:
• If your system includes a multi-channel controller, set the
center channel to use an 80 Hz crossover. Some controllers
or receivers refer to this setting as a “small” center channel.
• Use an 80 Hz crossover even if your system does not include
a subwoofer. In its absence, the multi-channel controller or
receiver will use “bass management” techniques to route the
frequencies below 80 Hz to the front left and right channels.
As a result, no center-channel low-frequency information
will be lost.
• The use of an 80 Hz crossover will result in dramatically
decreased distortion, accurate timbre, and greatly increased
dynamic capability.
• Please contact your Revel dealer for assistance in properly
adjusting the crossover settings on your multi-channel
controller or receiver.
3. Initially set the PLACEMENT COMPENSATION control (see
Figure 15 on previous page) to match the application as follows:
• Use the Flush Mounted setting when the loudspeaker is
flush-mounted in a wall or custom-built “media wall,” or is
placed on a bookshelf.
• Use the On Top of Monitor setting when the loudspeaker is
placed on top of a rear projection or direct view monitor.
• Use the Stand Mounted setting when the loudspeaker is
placed on its (optional) pedestal.
4. Turn on the system power and play a variety of material. Slowly
increase the volume to a comfortable level and listen from your
main listening position. Be sure to set your multi-channel controller to a mode that utilizes the center channel. If the REVEL
PERFORMA C50 loudspeaker is used in a home theater system,
listen to well-recorded dialog from more than one film, as the
sound quality can vary greatly.
5. Experiment with setting the PLACEMENT COMPENSATION
control. It provides a powerful means to correct for the placement effect on the REVEL PERFORMA C50’s “timbre,” or
overall balance. Due to the influence of room acoustics, you
REVEL PERFORMA C50
Owner’s Manual
16
Page 17
may achieve a better timbre match with the left and right
(front) loudspeakers than your original setting (as performed
in step 2 on the previous page). Experimentation is the best way
to determine the optimum setting.
NOTE: Rotating the PLACEMENT COMPENSATION control to
the right increases low-frequency output (see Figure 15 on page 15).
6. You may also wish to further adjust the tweeter’s HIGH
FREQUENCY LEVEL control (see Figure 15 on page 15) to
achieve the most natural sound in your room. Var ying the
control will change the high frequency balance and timbre.
CABINET CARE
The cabinet for the REVEL PERFORMA C50 loudspeaker has a
wood veneer finish and does not require any routine maintenance.
Occasionally, use a soft cloth, dampened with household furniture
polish, to remove any fingerprints or dust. Clean the grille by gentle vacuuming.
LOUDSPEAKERS AND POWER
A REVEL PERFORMA C50 loudspeaker uses high-order
crossovers with steep cut-offs to eliminate damage caused by “out
of band” frequencies. Using this approach, in combination with
carefully selected components and transducers, gives us confidence
that a REVEL PERFORMA C50 loudspeaker will not fail, even
under extreme conditions.
However, there is a limit to how loudany speaker can play
continuously. A good rule of thumb is to avoid playing the system
at volume levels beyond where the sound is “clear.” If the sound
becomes distorted or strained, reduce the volume level immediately
to avoid damage.
If you are unsure of the suitability of current or planned amplifier
components, please ask your Revel dealer to review them before connecting your REVEL PERFORMA C50 center-channel loudspeaker.
NOTE: Also refer to step 2 (on the previous page) for 80 Hz
crossover requirements.

SPECIFICATIONS
Revel utilizes proprietary measurement methods in the design and
specification of our loudspeakers. Our research has developed a
series of tests that represent a great leap forward in making measurements that dramatically contribute to our goal of accurately
reproducing music or film.
Sensitivity: 90 dB SPL, with 2.83 V
rms
@ 1 m
(4 pi anechoic)
Sensitivity provides an indication of how much amplifier power is required
for the loudspeaker to play at satisfactory volume levels. This conservativelyrated specification indicates high sensitivity and denotes that the REVEL
PERFORMA C50 loudspeaker does not require huge amplifiers to achieve
realistic levels in all but the largest rooms.
Impedance: 5.7 ohms (nominal), 3.2 ohms (minimum)
@ 200 Hz (stand position)
Impedance indicates whether the speaker system presents a “hard” or
“easy” load on the amplifier. A minimum impedance value of
3.2 ohms, together with moderate phase angles, signifies that any
competently-designed amplifier can easily drive the REVEL PERFORMA C50 loudspeaker.
Filters (Crossover): 3-way, high-order, acoustic response at 260 Hz
and 2.1 kHz
The steep filter slopes ensure good acoustical behavior in the
crossover regions, with a minimum of acoustical interference, along
with low distortion and wide dynamic range. The filters feature
specially selected components. Woofer and tweeter filter boards are
physically independent.
Frequency Responses: In-Room Response;
±1.0 dB from 80 Hz to 18 kHz
In-room response is a breakthrough measurement that, in a single
curve, closely correlates to sound quality and has been a goal of loudspeaker engineers for years. Research, and simple observation, reveals
that ubiquitous “on-axis” response curves often cannot distinguish
between two loudspeakers with radically different sound quality. This
REVEL PERFORMA C50 loudspeaker specification is even more
powerful when it is taken in context with the other measurements
presented here.
In-Room Response Relative to Target Response;
±0.75 dB from 90 Hz to 16 kHz
A target response is the ideal response goal and is not flat at the frequency extremes and is used when the ideal reference is not a “flat”
line. A target response must be tailored to the loudspeaker’s intended
application and takes into account the acoustic impact of the loudspeaker’s location, such as freestanding, or placement near a wall.
First-Reflections Response;
±1.0 dB from 80 Hz to 16 kHz
First reflection response is a measure of the response a listener
hears that is contributed by the first reflections from the walls,
floor, and ceiling. This superb specification indicates that REVEL
PERFORMA C50 loudspeaker will remain accurate, even in the
presence of strong reflections.

C50 loudspeaker.
SPECIFICATIONS (Continued)
Frequency Responses: Listening Window Response;
(Continued) ±1.0 dB from 70 Hz to 18 kHz
This improved “on-axis” measurement reduces the visual confusion
of inaudible local interference, yet still retains full accuracy without
using “spectral smoothing” which results in significant data loss.
Low Frequency Extension;
-3 dB @ 62 Hz (-6 dB @ 50 Hz,-10 dB @ 38 Hz)
Studies have shown that the -10 dB low frequency extension specification is the one that best correlates to controlled listening tests.
At low frequencies, most loudspeaker/room combinations will
exhibit significant “room gain”, which is an increasing rise in level
as frequencies decrease. In addition, the -10 dB specification reflects
the steepness (i.e., order) of the low-frequency roll-off, which is not
significantly indicated in -3 dB specifications.
