ABOUT THE REVEL® CONCERTA™ B1 SUBWOOFER Thank you for purchasing the Revel Concerta B1, a high-performance powered subwoofer that perfectly augments Revel Concerta Series loudspeakers in stereo music or home theater entertainment systems. The B1’s adjustable controls and multiple connection options also allow you to optimize the subwoofer’s performance in any system and listening room. Featuring a 12" (305mm) woofer with 1-1/2" (38.
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
Rooms with multiple seating rows PLACING A SINGLE SUBWOOFER 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. 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.
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 B1 subwoofer. MAKING CONNECTIONS CAUTION: Never make or break connections unless all system components are powered off.
