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.

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
