B1
 
The Revel B1 is a high-performance powered subwoofer, designed to add essential bass response to any music or home theater system. The B1 subwoofer delivers accurate and authoritative bass from a surprisingly compact enclosure. Adjustable controls, parametric room equalization and multiple connection options provide unequalled placement flexibility and allow you to optimize low-frequency performance for any listening environment.

Highlights
Woofer composed of micro ceramic composite (MCC) allows for strength and stiffness but very little weight.
Nomex/cotton blend spider for increased linearity.
2” (51mm)-diameter copper voice coil would on a Kapton bobbin for impressive power handling.
Parametric room EQ functions
Downward-firing port allows for placement against a wall or cabinet.
