CABINET

Minimizes cabinet-induced colorations with 1-inch (25mm) thick

walls and extensive internal bracing. For even greater sound

enhancement, rounded baffle edges minimize diffraction and opti-

mize treble response. Adjustable spike footing is attached to the

bottom of the cabinet for optimal stability, accommodating

installations on tile, hardwood, and carpeted floors. Refer to the

Adjustable Spike Footing section on page 9.

The cabinet’s wood veneer finish does not require routine mainte-

nance. However, cabinet surfaces that have been marked with

fingerprints, dust, or other dirt can be cleaned using a soft cloth

and a high-quality furniture polish. If a higher-gloss finish is

desired, a high-quality wax can also be used.

To clean the cabinet:

1. Apply a high-quality furniture polish to a soft cloth.

2. Use the cloth to lightly wipe the cabinet surface.

To clean the grille:

Gently vacuum using a soft bristled brush vacuum attachment.

CAUTION: To prevent cabinet damage, do not use a cloth made

with steel wool or metal polish to clean the cabinet. To prevent

possible transducer damage, do not apply furniture polish directly

to the cabinet.

UNPACKING

The F50a requires special care and handling during unpacking.

Figure 6. F50a room placement

PLACEMENT

Sound quality is heavily dependent on the accuracy of your loudspeak-

ers, their placement in the listening room, and the acoustics of the

room itself. Since the F50a loudspeakers are extremely accurate, experi-

menting with their placement is the most significant way to optimize

their performance in a given environment. The following guidelines

will help you obtain the best results:

•For best stereo imaging, place the F50a loudspeakers at equal

distances from the main listening position and in symmetry

with the room, as shown in Figure 6.

•Optimum timbre and imaging precision is obtained with the

loudspeakers pointing almost directly toward the prime listen-

ing position. Some listeners prefer a wider “soundstage,” which

is achieved by reducing the toe-in angle, perhaps to the point of

aiming the loudspeakers straight ahead.

•Imaging and a sense of spaciousness will improve as the

loudspeakers are moved away from the wall behind the loud-

speakers and the side walls.

NOTE: You may then need to move the listening position back to

maintain the best stereo image.

•For more bass reinforcement, try moving the loudspeakers closer

to the front wall or corners (also see Room Acoustics on next page).

NOTE: You may then need to move the listening position forward

to maintain an acceptable stereo image.

•For best results, make sure there are no objects between the F50a

loudspeakers and the intended listening area (e.g., a coffee table

in front of the listener will degrade timbre and imaging). If possi-

ble, avoid placing the loudspeakers near large objects, which can

cause unwanted reflections.

•Ideally, the listening room should be acoustically neutral,

neither producing any distinct echoes nor sounding completely

“dead” (also see Room Treatment on the next page).

ROOM ACOUSTICS

Listening rooms have a profound impact on sound quality, espe-

cially at low frequencies. In fact, a listening room can actually

dominate the sound quality below about 300Hz. Ideally, a new

room being built from scratch would include optimized dimen-

sional ratios to minimize the effects of standing waves.

However, most installations will be made in existing rooms. In

these cases, your only solution is to take special care in selecting

both the speaker and prime listening locations, which will pay off

in superior low frequency performance. Often the difference

between poor and excellent results is the result of relatively small

adjustments in speaker and listener placements.

The interaction of loudspeakers and rooms is quite complex, as the

loudspeaker and listener are affected by two mechanisms. First,

nearby surfaces, or boundaries, cause large peaks and dips in low

frequency response. These peaks and dips can often range 12dB or

more. Second, the loudspeaker and listener locations interact with

the standing waves, or room modes. These standing waves, or reso-

nances, also result in large response errors. There are no simple

formulas that take both mechanisms into account. Even computer

programs that analyze one or both factors still may not provide

you with the proper speaker or listener placement values.

Here’s where real-world experience counts. Consult an authorized

Revel dealer for help in determining the optimum loudspeaker and

listener placement for your listening room.

REVEL PERFORMA F50a

Owner’s Manual

IMPORTANT

ROOM TREATMENT

F50a loudspeakers have very accurate off-axis response, which

minimizes any degradation caused by overly “live” rooms.

However, superior performance will be achieved by placing mini-

mal acoustic treatment materials at the primary reflection points.

Ideally, special acoustic absorbers should be placed at the first

reflection points on the side and front walls along with either

absorbers or diffusers at the first reflection points on the front and

rear wall. Short of using acoustic treatment materials, even hanging

rugs can be a great help in overly bright rooms. Carpeting the floor

area between the speakers and listener and placing irregular

surfaces, such as bookcases, will also help break up strong reflec-

tions.

Since our ears and eyes are located on the same plane, we can use a

mirror (also known as the “mirror method”) to accurately deter-

mine the most important locations (the first reflection points) for

acoustic treatment, as follows:

1. After the loudspeakers are placed, the listener should sit in the

prime listening position. If additional seating locations will be

used, try all listening positions during this process to ensure that

the treatment materials adequately cover the listening areas.

2. A second person should slide a mirror along the walls.

3. Note the locations at which the listener can see either of the

loudspeakers. These will be the reflection points that would

require acoustic treatment materials.

Using this method, find all treatment locations for side walls, the

front wall, and rear walls with side walls taking priority. Where

possible, also determine the treatment locations for first ceiling

reflections.

An authorized Revel dealer can recommend acoustic treatment

materials, and can help determine the best plan for the listening

room. If it is a dedicated listening room, qualified room treatment

manufacturers or even acousticians may be consulted for optimum

results. Remember, properly treated rooms provide dramatically

better results with any loudspeakers than untreated rooms.

CONNECTIONS

Revel Performa F50a loudspeakers can be connected to your audio

system in three different ways: single-wired, bi-wired, or bi-ampli-

fied. Please read the following three sections before proceeding with

the actual connections. Also, be sure to observe the following

points:

•Use high-quality speaker cable with a maximum total loop resis-

tance (for each wire run) of 0.07 ohms or less. Use the chart in

Figure 7 below to determine the maximum wire gauge.

NOTE: A high loop resistance will result in mis-termination of the fil-

ter networks, and serious degradation of sound quality. Use high-qual-

ity connectors on the speaker cables. Consult an authorized Revel deal-

er 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. Failure to do so will cause poor imaging and

diminished bass response.

•For bi-wired or bi-amplified applications, remove the shorting

straps on the rear of each F50a loudspeaker (refer to Figures 8,

9, and 10 on the next three pages).

SYSTEM OPTIMIZATION

1. After connecting the F50a loudspeakers, initially set the

TWEETER LEVEL CONTROL on both rear panels to the

“0” position, as shown in Figure 12 (below).

2. Turn on the system power and play a favorite piece of music.

Slowly increase the volume to a comfortable level and listen

from your main listening position. If desired, experiment with

placement (see page 8) to achieve the best overall tonal balance,

image specificity, and spaciousness.

3. You may also wish to further adjust each TWEETER LEVEL

CONTROL. Varying the control will change the high frequency

balance and timbre. Differences in room acoustics often demand

different level control settings.

NOTE: Set the controls the same on both left and right channels.

LOUDSPEAKERS AND POWER

Revel Performa F50a loudspeakers use high-order crossovers with

steep roll-offs to minimize damage caused by “out of band”

frequencies. Using this approach, in combination with carefully

selected components and transducers, helps minimize the potential

for loudspeaker failure, even under extreme conditions. However,

there is a limit to how loud any speaker can play continuously.

Avoid playing the system at volume levels beyond where the sound

is “clean.” If the sound becomes distorted or strained, reduce the

volume level immediately to avoid damage.

If unsure of the suitability of current or planned amplifier compo-

nents, please ask an authorized Revel dealer to review them before

connecting the F50a loudspeakers.

from 33Hz to 19kHz

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 @ 23Hz

- 6dB @ 27Hz

- 3dB @ 32Hz

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 @

225Hz and 2.3kHz

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.
