ABOUT THE F32

Thank you for purchasing the Revel
Performa F32 Floor-Standing Loudspeaker.
A true full-range reproducer, the F32 delivers
an impressive combination of expansive
frequency response, low distortion, and
maximum output across the entire audible
spectrum. Four proprietary transducers,
sophisticated filter networks, and an
acoustically inert cabinet allow the F32 to
achieve acoustical precision and performance
befitting the most demanding home
entertainment systems.

A critical aspect of loudspeaker design,
transducers convert electrical signals into
audible sounds, profoundly affecting
loudspeaker performance. Combining
superior form and function, the F32
transducers feature a distinctive design
that allows for smoother frequency
response. The woofer and midrange cones
are constructed with Organic Ceramic
Composite cone material to reduce
distortion, while the spiders are constructed
with a high-strength Nomex blend with
optimized geometry for increased linearity.

A three-way design, the F32 transducers
effectively cover the entire audible spectrum.
Two 6.5-inch (165mm) woofers deliver
highly refined and dynamically authoritative
low frequencies down to the very lowest
octaves. Housed in its own sub-enclosure, a

5.25-inch (133mm) 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 audible levels, with wide dispersion
for open, airy treble.

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 220Hz and 2.8kHz
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 shorting­straps and gold-plated binding posts
accommodate single-wired, bi-wired, and
bi-amplified connections, while separate
Low Frequency Compensation and Tweeter
Level controls provide precise balance to
compensate for less-than-ideal listening
room acoustics and loudspeaker placement.

The F32 cabinet is constructed with 1-inch
(25mm) 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. Adjustable
spike footing is attached to the bottom of the
cabinet for optimal stability, accommodating
installations on tile, hardwood, and carpeted
floors. 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 cutting-edge
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.

5

Adding to the proud lineage of Revel’s
Ultima and Performa Series Loudspeakers,
the F32 further advances Revel’s reputation
as the leading designer and manufacturer
of high-quality, high-performance loudspeak­ers. Each F32 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 F32 is an ideal match for most
home entertainment systems.

INSTALLATION
CONSIDERATIONS

Loudspeaker fidelity depends on the following
three factors:

1. Loudspeaker accuracy

2. Loudspeaker placement

3. Listening room acoustics

Advanced Revel design features allow the
F32 to achieve exceptional acoustical
precision. Each F32 is individually hand­tuned during manufacturing to match the
production reference standard within a
fraction of a decibel, ensuring incomparable
loudspeaker-to-loudspeaker consistency. As
a result, experimenting with loudspeaker
placement and listening room acoustics
have the most significant impact on the
F32’s performance.

LOUDSPEAKER PLACEMENT

The bulleted items that begin below
indicate important loudspeaker placement
considerations for the F32.

• Remove all obstructions between the
F32 and the primary listening position.
For instance, a coffee table between the
F32 and the primary listening position
will degrade stereo imaging and timbre.
Placing the F32s near large objects may
also cause unwanted reflections.

• For the best stereo imaging, place the
F32s at equal distances from the
primary listening position and the side
walls as shown in Figure 6 at the top of
the next page.

11

• For optimal stereo imaging and timbre,
point the F32s almost directly toward
the primary listening position as
shown in Figure 6 (above). The toe-in
angle can be reduced to widen the
soundstage, even to the point at which
the F32s are pointing straight forward.

• Move the F32s farther from the front
and side listening room walls to
improve stereo imaging and the sense
of spaciousness in the listening space.

• Move the F32s closer to the corners or
walls of the listening room to increase
bass response.

LISTENING ROOM ACOUSTICS

Listening rooms have a profound impact
on sound, particularly at lower frequencies.
In fact, listening rooms can dominate
sounds below about 400Hz. Ideally, listening
rooms would include optimized dimensional
ratios to minimize the effects of room
resonances. But in reality, most listening
rooms are not designed to enhance
loudspeaker performance.

The interaction between loudspeakers and
listening rooms is complex, depending on
two important determinants that affect the
loudspeaker and the listener.

1. Surfaces and other boundaries often
cause large peaks and dips in low­frequency extension. These peaks and
dips often range 12dB or more.

2. Standing waves (also known as room
modes or resonances) interact with
both the loudspeaker and the listener,
resulting in large frequency response
errors.

Unfortunately, there is no simple solution
that considers both factors. Even computer
software programs that examine both
factors may not calculate proper primary
listening position or loudspeaker place­ment values.

In most cases, proper selection of the
primary listening position combined with
proper placement of the loudspeaker can
still result in superior performance at lower
frequencies. The difference between superior
and inferior results is often just a small
adjustment of the primary listening position
or loudspeaker placement. Contact an
authorized Revel dealer for assistance.

Acoustic Treatment Materials

The F32 features high-order filters at 220Hz
and 2.8kHz that optimize loudspeaker on and
off-axis response, minimizing degradations
that occur in overly “live” rooms. Placing
acoustic treatment materials at primary
reflection points will reduce these distor­tions even further. Ideally, acoustic
absorbers should be placed at the first
reflection points on the front and side walls
and either acoustic absorbers or diffusers
should be placed at the first reflection
point on the rear wall.

Because the listener’s eyes and ears are on
the same plane, the “mirror method” is an
accurate determinant of critical reflection
points. This method can be used to determine
reflection points for side walls, rear walls,
front walls, and even the ceiling. Applying
acoustic treatment materials to the side
walls is most important, followed by the
front wall, rear wall, and ceiling.

To determine reflection points using the
mirror method:

1. Once the F32s have been placed, sit in
the primary listening position.

2. Ask another person to slide a mirror
along the listening room walls.

3. Note the locations at which the person
sitting in the primary listening position
can see either F32. Be sure to look for
both F32s in the reflection on each
room boundary. These are primary
reflection points that will most benefit
from acoustic treatment materials.

If acoustic treatment materials are not
available, hanging a rug over the reflection
points will help to reduce degradation in
overly “live” rooms. Carpeting the floor
between the loudspeakers and the primary
listening position and placing irregular
surfaces such as bookcases at first reflection
points will also help minimize strong
reflections.

ADJUSTABLE SPIKE FOOTING

When shipped, adjustable spike footing is
attached to the bottom of the cabinet for
optimal stability, accommodating
installations on tile, hardwood, and carpeted
floors. The F32 is shipped with spike footing
attached as shown on the left side of Figure
7 at the top of the next page, with the
round end protruding from the cabinet.
The protective cap is placed over the round
end to protect tile and hardwood floors.

Note

When moving the F32, do not drag it
across the floor.

If the F32 is placed on a carpeted floor, the
spike footing should be adjusted as shown
on the right side of Figure 7 (next page),
with the spike end protruding from the
cabinet. If needed, follow the instructions
that begin below to adjust the spike footing.

To adjust the spike footing:

1. Place the F32 on its side on a soft towel
or carpeted floor.

2. Remove the protective cap from the
round end of the spike. Save it for
possible future use.

3. Rotate the locking ring counterclockwise
to detach it from the spike. Save it for
use in step 6.

4. Rotate the spike counterclockwise to
remove it from the cabinet.

5. Rotate the spike clockwise into the
cabinet, round end first, as shown on
the right side of Figure 7 (next page).

13

6. Reattach the locking ring, rotating it
clockwise to firmly secure the spike to
the cabinet.

7. Repeat steps 2 through 6 for the
remaining three spikes.

8. When all four spikes have been reversed,
stand the F32 in the upright position. If
needed, repeat steps 1 and 6 to achieve
a level balance.

9. Repeat these steps to adjust the spike
footing on the other F32.

CAUTION

Floor-standing loudspeakers such as the
F32 have a high center of gravity, which
may cause them to fall if tipped or
improperly positioned.To avoid this,
anchor the loudspeaker to the floor
and/or wall 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.

MAKING
CONNECTIONS

The F32 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 5 (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:

• Make all connections observing the
proper polarity, positive-to-positive (+)
and negative-to-negative (–).
Connections that do not observe the
proper polarity will cause poor stereo
imaging and diminished bass response.

•Vertical bi-amplified connections must
be made with identical power amplifiers.
Horizontal bi-amplified connections
can be made with identical or non­identical 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.

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

Note

High loop resistances that exceed 0.07ohms
(for each wire run) will cause the filter
network to mis-terminate, resulting in
considerable degradation of sound quality.

• If desired, contact an authorized Revel
dealer for information about the
suitability of power amplifier components
before connecting the F32 to the
associated power amplifier.

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

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
does not offer two connectors per output
channel.

To make vertical bi-amplified connections:

1. Remove the input panel shorting-straps

identified in Figure 5 (page 9).

2. Connect one pair of loudspeaker wires

to the F32 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 F32 input connectors
labeled Low Frequency. Then, connect
the same pair of loudspeaker wires to a
separate output channel on the same
power amplifier.

4. Repeat steps 2 and 3 to connect both

pairs of input connectors on the second
F32 to another, identical power ampli­fier.

Note

Vertical bi-amplified connections must be
made using two identical power amplifiers.

HORIZONTAL BI-AMPLIFIED
CONNECTIONS

Horizontal bi-amplified connections are
made between both pairs of F32 input con­nectors and two separate output channels
on two separate power amplifiers. The F32
input connectors labeled High Frequency
are connected to one power amplifier,
while the F32 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 11 at the
bottom 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 5 (page 9).

2. Connect one pair of loudspeaker wires
to the F32 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 F32 input connectors
labeled Low Frequency. Then, connect
the same pair of loudspeaker wires to
the desired output channel on another
power amplifier.

4. Repeat step 2 to connect the input con­nector labeled High Frequency on the
second F32 to the same power amplifier
that was selected in step 2.

Note

Horizontal bi-amplified connections can
be made using identical or non-identical
power amplifiers. However, these power
amplifiers 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. Contact an authorized Revel
dealer for assistance.

5. Repeat step 3 to connect the input
connectors labeled Low Frequency on
the second F32 to the same power
amplifier that was selected in step 3.

OPTIMIZING
PERFORMANCE

To optimize the F32 for best performance:

1. Set the Tweeter Level control to 0.
(Different listening rooms may require
other Tweeter Level control settings.)

2. Set the Low Frequency Compensation
control to the appropriate position.

• Select the Normal setting if the

loudspeaker is located at least 3
feet (0.91m) from walls and other
objects.

• Select the Contour setting to reduce

low-frequency signal levels.

• Select the Boundary setting if the

loudspeaker is built into an
entertainment center or shelving
unit or if the loudspeaker is located
less than about 2 feet (0.61m) from
walls and other objects.

3. Begin playback of a familiar music or
film source.

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

5. Experiment with the F32’s placement
to achieve the best overall tonal
balance, image precision, and sense of
spaciousness in the listening room.
Refer to the Loudspeaker Placement
section that begins on page 10 for
additional information about
loudspeaker placement.

6. Adjust the Tweeter Level control on
each F32 to change high-frequency
balance and timbre.

7. Repeat these steps to optimize
performance of the second F32.

Note

For best results, set the Tweeter Level
control on both F32s to the same position.

LOUDSPEAKER VOLUME LEVELS

High-order filters include steep cut-offs to
reduce potential damage from “out-of­band” frequencies. Combined with carefully
selected transducers and filter network
components, this approach helps the F32
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

If desired, contact an authorized Revel
dealer for information about the suitability
of power amplifier components before
connecting the F32 to the associated
power amplifier.

SPECIFICATIONS

Definition

Sensitivity

Impedance

86.5dB SPL
with 2.83Vrms @ 1m
(4 pi anechoic)

6.5Ω (nominal)

3.7Ω (minimum @ 260Hz)

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 33Hz 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 34Hz to 20Hz

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 33Hz 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 31Hz to 16kHz

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 @ 24Hz

- 6dB @ 26Hz

- 3dB @ 30Hz

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 @
190Hz 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 bi­amplified connections as well as flexible controls for user
adjustments.
