B10 Subwoofer
Owner’s Manual
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.

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.

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.
