on each room boundary. These are reflection points that require acoustic treatment
materials.
If acoustic treatment materials are not available, hanging a rug over the reflection points
will help reduce sonic degradation in overly “live” rooms. Carpeting the floor area between
the loudspeakers and the primary listening position and placing irregular surfaces such as
bookcases at the first reflection points will also help minimize strong reflections.
MAKING CONNECTIONS
CAUTION: Never make or break connections unless all system components are powered
off.
BINDING POSTS
These gold-plated terminals provide connections from the power amplifier(s) to provide
secure connection for speaker cables terminated with banana plugs, spade lugs, pin
connectors or bare wire.
OBSERVE PROPER POLARITY
Connect the amplifier’s positive (+) terminal to the positive (+) terminal on the corresponding
speaker; connect the amplifier’s negative (–) terminal to the negative (–) terminal on the
corresponding speaker. Do not reverse polarities (that is, do not connect + to –, or – to +)
when making connections. Doing so will cause poor stereo imaging and diminished bass
response.
SPEAKER CABLE
Use high-quality loudspeaker cable with a maximum total loop resistance of 0.07 Ohms or
less for each wire run. Refer to the table below to determine the appropriate wire gauge for
your installation.
MINIMUM WIRE GAUGE
Maximum Wire
Length (Feet)
Maximum Wire
Length (Meters)
Minimum Wire
Gauge (AWG)
<87 <27 6
<69 <21 7
<58 <18 8
<43 <13 9
<34 <10 10
<27 <8 11
<22 <7 12
<17 <5 13
<14 <4 14
<11 <3.5 15
<9 <3 16
<7 <2 17
<5 <1.5 18
NOTE: High loop resistances that exceed 0.07 Ohms (for each wire run) will cause the
loudspeaker’s filter network to be mis- terminated, resulting in considerable degradation
of sound quality.
F328Be
The F328Be has one pair of high frequency and one pair of low frequency binding posts that
come from the factory connected by a pair of shorting straps (see below). The two sets of
binding posts can be configured for single-wire, bi-wired, or bi-amped connections. See the
instructions on this page through page 10 for additional information.

Shorting Straps
Before making connections to the F328Be speakers note the following:
• The standard connection method uses a single loudspeaker cable. The F328Be is
equipped with two pairs of input terminals to allow for bi-wiring or bi-amping. While
Revel does not endorse one particular connection method over another, these additional
connection options are available if desired. The design of this loudspeaker is such that
optimal performance can be attained using the standard connection method.
• Vertical bi-amped connections (see below) must be made with identical power
amplifiers. Horizontal bi-amped connections (see below) can be made with identical or
non-identical power amplifiers with identical gain factors.
• When making bi-amped connections, both power amplifiers must receive identical
input signals from the associated preamplifier. If the associated preamplifier offers two
connectors per output channel, each power amplifier can be connected to a separate
connector for the same output channel of the preamplifier. If the associated preamplifier
does not offer two connectors per output channel “Y” adaptors are required.
• No matter which connection method you choose, the speaker cables used for the left
and right loudspeakers should always be the same length.
• If desired, contact your authorized Revel dealer for information about the suitability of
power amplifier components before connecting the F328Be to your power amplifier(s).
• Review the owner’s manuals for all associated audio components to determine their
correct connection procedures.
NOTE: Do not use an electronic crossover network when bi-amping Revel F328Be
loudspeakers. Doing so will cause a considerable degradation of sound quality.
SINGLE-WIRED CONNECTION
NOTE: Do not remove the shorting straps between the speaker terminals.
Single-wired connections are the most common. These are made between one pair of
F328Be input terminals and one power amplifier output channel as shown below.
