ABOUT THE REVEL®CONCERTA 2™
B10 SUBWOOFER
Thank you for purchasing the Revel Concerta 2 B10, a high-performance
powered subwoofer that perfectly augments Revel Concerta 2 Series
loudspeakers in stereo music or home theater entertainment systems.
The B10’s adjustable controls allow you to optimize the subwoofer’s
performance in any system and listening room.
Featuring a 10" (254mm) woofer with 1-1/2" (26mm) peak-to-peak
excursion and powered by a 800-watt amplifier, the B10 subwoofer
reproduces deep, realistic bass with very low distortion, even at the
lowest frequencies and high output levels.
Combining superior form and function, the B10’s proprietary woofer is
constructed with an polycellulose fiber diaphragm for great strength at
high output levels. The spider incorporates a superior-strength Corex/
cotton blend with optimized geometry for increased linearity. The motor
includes a large ceramic-magnet motor system. A 2.6" (50.8mm) copper
voice coil is wound on a Kapton®bobbin for impressive power handling
and freedom from compression. The vented center pole facilitates
heat dissipation, allowing more efficient high-power handling and low
compression.
The B10 cabinet consists of medium-density fiberboard (MDF) walls and
extensive internal bracing to reduce cabinet-induced colorations. Rubber
padded feet are attached to the bottom of the cabinet for optimal
stability, accommodating installations on any floor surface.
Since 1996, the Revel brand has been at the forefront of loudspeaker
design. Backed by Harman International’s extensive research and design
facilities, Revel Concerta 2 Series speakers benefit from cutting-edge
development tools, such as:
• A multichannel listening lab allows for double-blind listening tests.
• A laser interferometer enables detailed driver and cabinet analysis.
• Multiple large anechoic chambers provide for precise tests and
measurements.
• Finite-element analysis allows for advanced loudspeaker modeling.
• A stereo lithography apparatus aids in achieving tight tolerances.
Adding to the proud lineage of Revel Ultima™ and Performa™ Series
loudspeakers, the subwoofer further substantiates the Revel reputation
for high-quality, high-performance loudspeakers and subwoofers.

SUBWOOFER PLACEMENT
Below 300Hz, loudspeaker and listener locations have a profound impact
on the way sound is reproduced. All rooms have “standing waves,” by
which certain frequencies are emphasized or diminished. Their complex
patterns can combine to introduce tremendous sound coloration at low
frequencies.
The Concerta 2 B10’s Equalization controls can help to compensate for
these effects, but no electronic system alone can fully compensate for
the dramatic effects of room acoustics. Every room has locations where
“nulls” at specific frequencies occur. These cancellations of the sound
are like “black holes,” which no amount of equalization can fill. The
best results are always achieved through careful placement of both the
loudspeakers and the listening position. Preferable placement can be
determined through the use of computer modeling programs, or by trial-
and-error measurements. For optimal results, find the best loudspeaker
and listener locations first, then use the B10 Equalization controls for
fine-tune adjustments.
To help determine good locations for the subwoofer(s) and the
listener(s), it is recommended that you make high-resolution in-room
response measurements. Your authorized Revel dealer can make the
appropriate measurements, using suitable equipment to ensure optimal
results.
NOTE: Many sound-measurement devices are not accurate
enough to properly measure low-frequency performance in a
listening room, since room boundaries can often cause modes
(standing waves) with very narrow-band peaks and dips.
Check with your authorized Revel dealer to confirm that your
measurement equipment is suitable for accurate, high-resolution
measurements.

SUBWOOFER PLACEMENT
CONSIDERATIONS
When using subwoofers within the limited confines of a typical home
theater room, the reflections, standing waves and absorptions generated
within the room will create peaks and dips in the bass response that
can vary greatly depending on where the listeners are located in the
room – a listener seated in one location may hear an overabundance of
bass created by a response peak at that location, while another listener
only a few feet away may hear a considerable lack of bass created by a
response dip at that location.
The subwoofers’ locations within the room (along with the room’s
dimensions) also have a profound effect on the creation of these bass
response peaks and dips. Careful subwoofer placement alone cannot
compensate for all bass response peaks and dips throughout a room, but
careful subwoofer placement can eliminate or significantly reduce the
largest response dips.
It is important to reduce response dips throughout the room as much as
possible via proper subwoofer placement because equalization cannot
be used to compensate for large response dips. For example, using
equalization in an attempt to restore a 13dB response dip requires
that the subwoofer amplifier delivers twenty times the power at that
frequency. This can quickly overdrive the subwoofer amplifier into
clipping, which will significantly degrade audio quality.
In almost any room, placing the subwoofers in corners will produce the
fewest large bass response dips and will also produce the most large
bass response peaks.
We strongly recommend that you install multiple subwoofers regardless
of the room’s size. Installing a single subwoofer will result in the least
consistent bass performance throughout the room. Using multiple
subwoofers can cancel some room modes at the various listening
locations, resulting in much more consistent low frequency sound
quality throughout the listening area. Additionally, it is often impossible
to locate a single subwoofer such that large response dips, which
cannot usually be corrected via equalization, are not present. The use of
two or more properly placed subwoofers can almost always eliminate
such dips in response.
PLACING FOUR SUBWOOFERS
When installing four subwoofers, place each one in a room corner. In
rooms with more than four corners, use the four corners closest to the
listening area.
Video Screen
PLACING TWO SUBWOOFERS
Placement of two subwoofers will be determined by your room’s seating
arrangement.
Rooms with a single row of seating
Placing the subwoofers in the two front corners will produce the most
consistent bass performance throughout a single row of seating.

Rooms with multiple seating rows
Placing one subwoofer in a front corner and the other subwoofer in the
rear corner on the same side will produce the most consistent bass
performance throughout multiple seating rows.
Video Screen
PLACING A SINGLE SUBWOOFER
When installing a single subwoofer, be prepared to experiment with
different locations to find the one that produces the best results
throughout your room’s seating area. As in the previous examples,
placing the subwoofer in a corner will produce the fewest number of
deep response dips, which cannot be corrected with equalization.
Video Screen
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 minimized or eliminated by the proper adjustment of
the Concerta 2 B10’s Equalization controls, but dips cannot be corrected
via equalization. Therefore, the most important objective is to find
locations that result in the minimum number (and severity) of dips.
Contact your authorized Revel dealer for assistance in determining the
proper placement of your Revel loudspeakers and subwoofers.
After placing the B10 subwoofer(s), 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 results in unnaturally “thick” or “boomy”
vocal reproduction. Bass response should not overpower the room, and
should be adjusted to achieve a harmonious blend across the entire
audible range.
If you are using a multichannel receiver or processor with a subwoofer
output, it’s preferable to use the Subwoofer Level adjustment on the
processor. Set the B10 Level control to the indicated “LFE” position.
NOTE: Setting the 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 level too high results in an overpowering bass
response. Setting the level too low negates the benefits of the
B10 subwoofer.

Figure 8: Rear-panel input connectors
The B10 subwoofer input connectors are located on the rear panel.
Some processors incorrectly label the subwoofer output as LFE; others
offer both an LFE and a Subwoofer output. If there is no labeled
subwoofer output, use the LFE output. If the output has labeled
connections for both LFE and Subwoofer, use the Subwoofer output.
The L (Left) and R (Right) connectors on the rear panel of the B10 can
be used with 2-channel applications, where there is no dedicated
subwoofer output available. These inputs are can be crossed-over by
the adjustable Low-Pass Crossover control on the rear panel. Having
the low-pass filter enabled helps offset the fact that most 2-channel
systems do not perform any high-pass filtering on the main speakers,
minimizing the advantages of using a subwoofer.

2. Connect an RCA patch cable between the right main output on the
receiver/preamplifier INPUT connector on the B10 rear panel.
NOTE: This configuration applies to receivers with preamplifier
outputs or to preamplifier/power amplifier configurations in which
there are two sets of Main outputs. If the receiver has jumpers
from the Pre- or Main-Out to the Amp in connectors or if the
preamplifier has only one set of Main-Out connectors, a
Y-adapter should be used to send the same signal to both the
main power amplifier and the subwoofer(s). Tape Out or Record
Out connectors cannot be used.

SUBWOOFER OPERATION
The rear panel of the Concerta 2 B10 subwoofer, shown in Figure 14,
contains all of the available connectors and controls. The Input section of
the rear panel was discussed in the “Making Connections” section, earlier
in this manual. The subwoofer controls are discussed in this section.
POWER INDICATOR LED
The Power Indicator LED identifies the current state of the B10 subwoofer.
The subwoofer has three different powered states:
Red: Standby – the B10 automatically enters Standby if no signal is
detected from the system for 10 minutes.
Green: On – as soon as a signal is detected, the B10 powers on.
No Light: Off - the main power switch is in the off position or unit is
unplugged.

Figure 15: Rear-panel controls and connectors
Adjusts the variable 50Hz – 150Hz low-pass crossover, which
determines the highest frequency at which the B10 reproduces sounds.
Set the crossover to a lower frequency setting, between 50Hz and
100Hz, when using larger main loudspeakers that can comfortably
reproduce some low-frequency sound.
With a lower frequency setting, the B10 subwoofer concentrates on
reproducing the deep bass required by contemporary music and film
soundtracks. Set the crossover to a higher frequency, between 100Hz
and 150Hz, for smaller bookshelf loudspeakers that do not extend to the
lower bass frequencies.
If the frequency control is set too high, the bass sounds “boomy” and
can overpower the overall sound of the listening room. If the frequency
control is set too low, some low frequency sound may be difficult to
hear, or may be absent altogether.
NOTE: This control does not limit the frequency range of the
main speakers in the system. The objective of adjusting the
Low-Pass Frequency control is to ensure that all frequencies
are reproduced while minimizing any overlap between the
subwoofers and the main speakers. Having both the subwoofer
and main speakers reproduce the same frequencies should
be avoided, as it results in very irregular response, since some
frequencies are reinforced when they happen to be in phase
while others are canceled because they are out of phase. When
set to “LFE” the crossover is in by-pass mode and all crossover
settings are now set by the Processor or AVR.
