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 Concerta2 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.
