ABOUT REVEL®
Since 1996, REVEL®has stood at the forefront of loudspeaker design
and performance. Backed by Harman International’s world leading
research and design facilities, REVEL®loudspeakers benefit from cutting
edge resources such as:
• Multiple large anechoic chambers which allow for precise testing
and measurements.
• A multi-channel listening lab for double-blind, position independent
listening tests.
• A laser interferometer that enables detailed driver and cabinet
analysis.
• Finite element analysis, utilized for advanced loudspeaker modeling.
• A stereo lithography apparatus, which rapidly “builds” tooled parts.
ABOUT YOUR REVEL®B28W IN-WALL SUBWOOFER
The B28W subwoofer is a dual 8” woofer high performance in-wall
subwoofer specifically designed to be used in conjunction with the
REVEL®SA1000 subwoofer amplifier. It is optimized to offer the best
dynamics and frequency response with use of the REVEL®SA1000
amplifier, which is specially designed to drive signature reactive load
impedance of the B28W.

The Revel®B28W is extremely easy to install. However, if you are
unable to understand and follow the instructions in this manual clearly
and fully, or if you are unsure of your ability to install these loudspeakers
properly, please contact your dealer or a qualified installer.
WARNING: HARMAN International assumes no responsibility for
improper installation of hardware or for any personal injuries or
product damages resulting from improper installation or a fallen
loudspeaker.
SPEAKER PLACEMENT
Low-frequency sounds are normally omnidirectional, meaning the
listener can’t tell where they are generated from. However, frequencies
between 75Hz and 150Hz can be localized, especially at higher volume
levels. Positioning your subwoofer as recommended will provide the
most natural soundstage and imaging from your loudspeaker system.
It is recommended that you install your B28W in-wall subwoofer along
the same wall as the front loudspeakers. The B28W subwoofer is not
video-shielded and should not be placed near a video display affected by
magnetic fields. Installing the B28W near a corner will tend to maximize
low-frequency output. Be cautious when installing in a corner, to avoid a
“boomy” sound. Also take into consideration any unusual features of the
room, such as an alcove, which may tend to create a localized node that
may affect bass response in that area of the room.
VIDEO
MONITOR
It is also recommended that the speaker be installed so that the bottom
of the speaker is approximately 12" from the floor. This is to help with
the low-frequency loading (bass reinforcement). This also helps hide the
speaker in a less visible place. In special circumstances it is acceptable
to install the speaker at any height on a wall.
When using two B28W in-wall subwoofer systems, you may need
to be concerned about phase, as the sound waves may cancel each
other out. If bass response seems low, try inverting the polarity on one
subwoofer – i.e., connect the (+) terminal on the amplifier to the (–)
terminal on the speaker, and the (–) terminal on the amplifier to the (+)
terminal on the speaker.
NOTE: Remember that these are just guidelines. Since every
listening room is different, we at Revel strongly recommend
experimenting with the positioning of your subwoofer prior to
cutting the wall to obtain the most pleasing results in your room.
One technique that can help you find the ideal subwoofer location
is to temporarily borrow a stand-alone subwoofer and place it
near the main listening location. Then move around the room and

4B28W In-Wall Subwoofer
Owner’s Manual
determine where you hear the most pleasing bass performance.
This would then be the ideal location for the subwoofer. To be
absolutely sure, we recommend placing your B28W as close as
possible to the intended location, and hooking it up to the SA1000
and a source. Then play some music or video clips to make sure it
will have the right character. Do not play the B28W too loudly, or
it will vibrate on the wall, possibly marking the wall.
CUTTING THE HOLE
First, use a pencil to mark the hole using the following dimension
drawing.
14.50in
(368.30mm)
23.50in
(596.90mm)
Then carefully use the sheetrock knife to cut the hole along your
markings. The hole should just fit between two studs, which the B28W
will use for isolation mount attachment.
RUNNING THE WIRE
CAUTION: REMOVE POWER
You must connect the speaker wires before the speaker is
fully installed. To protect the audio system and yourself from
damage or injury through accidental electrical shorting and
surges during installation, turn all audio system power OFF
before beginning the speaker installation.
At this point, it is a good time to run your wire from the SA1000
amplifier location to the hole that you cut for the B28W. Use high-quality
speaker wire to obtain the best performance from your Revel®B28W.
• For wire lengths of less than 50 ft (15m), use at least 16-gauge
speaker wire.
• For wire lengths between 50 ft and 100 ft (15m – 30m), use at least
12-gauge speaker wire.
• For wire lengths of greater than 100 ft (30m), use at least 10-gauge
speaker wire.
Note: All speaker wires must comply with all local building and
safety codes for use in in-wall applications.
Either place the B28W on a flat surface on its face, or have someone
hold it while you connect the wires to the gold-plated speaker terminals
at the top end. Push on the speaker terminal to open the wire hole and
insert the wire, positive lead to red, and negative lead to black. Make
sure that no stray wire strands touch the other speaker terminal.
CONNECTIONS
Use one side of the wire to connect one of the SA1000’s positive (+)
output terminal to the positive (red) terminal on the B28W. Most wires
have one lead with either printing, periodically spaced plus signs, or a
rib to differentiate it from the other lead just for this purpose. Use the
other lead of the pair to connect the associated negative (-) SA1000
terminal to the negative (black) terminal on the same B28W. It does not
matter which set of outputs a single B28W is connected to.
In general, do not reverse polarities (that is, do not connect the SA1000
+ output to the B28W – input, or the SA1000 – output to the B28W +
input) when making connections. In most rooms, doing so will cause
poor imaging and diminished bass response. In unusual rooms or
placements however, it might help to do this – see Troubleshooting,
below.
Press down on the post to open the hole; insert the bare end of the wire
into the hole and release the post to secure the wire.
CAUTION: To avoid short circuits that may damage your
equipment, be certain that positive and negative wire strands
do not touch each other and do not touch metal parts such as
the speaker frame.
CAUTION: When connecting two B28W subwoofers to one
SA1000, ALWAYS connect one to one output of the SA1000.
NEVER connect two B28Ws to one SA1000 output because
either the amplifier or speaker will be damaged.

INSTALLATION
Once the wire is attached to the B28W in-wall subwoofer, place the
subwoofer into the opening you have cut in your wall. The B28W is
designed for the terminals to point up as it sits in the wall.
When the B28W is in the wall, tighten the attachment screws at the top
and bottom. This will bind the wall to the dog-leg clamps at the ends of
the subwoofer. DO NOT OVER-TIGHTEN – at this point, they only need
to be firm.
Insert one mounting isolator into each of 8 openings. Next, put one
washer onto each included mounting screw, and insert this assembly
into the isolation mount through-hole.
Now tighten the isolator mount screws. This assembly will expand the
isolator mount to hold the subwoofer in the wall. The screws should be
firmly tightened enough to expand the isolator mounts, but do not need
to be tightened beyond this point.
After installation, play signal through the subwoofer. If there is any
buzzing or rattling coming from the B28W, adjust the mounting screw
tightness until it is gone.
PAINTING THE SPEAKER GRILLE
The B28W loudspeaker grille can be painted to match any décor. If you
wish to change the color, the satin finish on the grille will function as
a primer coat. Use a high-quality spray paint, and apply a thin coat of
color. Paint the grille separately from the baffle before installing it. After
painting the grille, remove and discard the scrim cloth attached to the
back side of the grille. If you choose to paint your grille, you may order
an extra scrim cloth by contacting us at the phone number located at the
end of this manual.

TROUBLESHOOTING
SYMPTOM SOLUTION
If there is no sound from any of the
speakers:
• Check that the source/receiver/SA1000 is on and playing.
• Check all wires and connections between the receiver/SA1000 and the speakers. Make sure all wires
are connected. Make sure none of the speaker wires are frayed, cut, punctured or touching each other.
• Review proper operation of your receiver/SA1000.
If there is no sound coming from one
speaker:
• Check the Balance control and channel output level settings on your receiver/SA1000.
• Check all wires and connections between the receiver/SA1000 and the speakers. Make sure all wires
are connected. Make sure none of the speaker wires are frayed, cut, punctured or touching each other.
In multichannel applications, make sure that your receiver/processor has been configured to enable all
channels that you are using.
If there is low (or no) bass output: • Make sure the connections to the speaker inputs have the correct polarity (+ and –). If you are using
two B28W subwoofers, try inverting the polarity on one subwoofer.
• In surround modes, make sure your receiver/ processor is correctly configured. Make sure the
subwoofer output of the receiver/processor has been enabled. See your receiver/ processor’s owner’s
manual for further information on correct speaker configuration in surround modes.
If the system plays at low volumes but
shuts off as volume is increased:
• Check all wires and connections between the receiver/SA1000 and all of the speakers. Make sure all
wires are connected. Make sure none of the speaker wires are frayed, cut, punctured or touching each
other. A shorting satellite speaker could shut the receiver down.
• If more than one pair of main speakers is being used, check the minimum-impedance requirements of
your receiver.
If you are hearing midrange frequencies
(such as vocals) through the subwoofer:
• Adjust the crossover frequency on your Revel SA1000 amplifier to a lower value.
EXCESSIVE OUTPUT LEVELS
Your Revel®loudspeakers feature custom-designed transducers and high quality network components featuring high-order filters with steep cutoffs
that reduce the potential of damage to individual speaker drivers and help the loudspeakers maintain their performance even 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
result in distorted or strained sound.
