Owner’s Manual
General Placement Guidelines
(continued)
• Another alternative is to place the four
B12s on the front and back walls one-
third of the distance into the room as
shown in Figure 12 (above).
• The placement of the other system
loudspeakers in the listening room will
also affect the way sound (below
300Hz) is reproduced. Just as you
would for the subwoofers, use a model-
ing program or trial-and-error meas-
urements to determine the best loca-
tions.
• Since listening and speaker locations
are equally important, the trial-and-
error process can be time consuming.
However, the sonic rewards are well
worth the time spent determining the
ideal placement locations. Remember
that peaks (below the subwoofer
crossover frequency) can be eliminated
by the proper adjustment of the
Concerta B12’s EQ controls, but dips
cannot be corrected. Therefore, the
most important objective is to find
locations that result in the minimum
number (and severity) of dips. See your
authorized Revel dealer for additional
information.

• After placing the B12s, begin playback
of a familiar music or film source that
has substantial bass content. Listen
from the primary listening position,
increasing the overall volume of the
system to a comfortable level. Adjust
the Subwoofer Level (Volume) Control
until you obtain the desired blend of
bass. Also, test the subwoofer level by
playing a recording of a deep male
voice. Setting the subwoofer level (or
crossover frequency) too high will
result in unnaturally “thick” or “boom-
ing” vocal reproduction. Bass response
should not overpower the room. The
bass should be adjusted to achieve a
harmonious blend across the entire
audible range.
• If you are using a multi-channel
receiver or processor with a subwoofer
output, it is preferable to use the sub-
woofer level adjustment on the proces-
sor. Set the B12 level control to the
indicated "Nominal" position.
Note
Setting the volume level of the subwoofer
in relation to the left and right front
speakers is of critical importance because
it is essential that the subwoofer integrate
smoothly with the entire system. Setting
the volume level too high will result in an
overpowering bass. Setting the volume
level too low will negate the benefits of the
B12.
