The Revel® Concerta™ B120 is a high-performance powered subwoofer, designed to add essential bass response to any music or home theater system, particularly those built around Revel Concerta Series loudspeakers.
The B120 subwoofer delivers accurate and authoritative bass from a surprisingly compact enclosure. Adjustable controls, parametric room equalization and multiple connection options provide unequaled placement flexibility, and allow you to optimize low-frequency performance for any listening environment. An optional wireless transmitter greatly simplifies installation. Featuring a 12” (305mm) woofer with 1½” (38mm) peak-to-peak excursion and a 250-watt (RMS) amplifier, the B120 adds serious punch with very low distortion, even at the lowest frequencies and at high output levels. A huge 2” (51mm)-diameter copper voice coil on a Kapton® bobbin, along with sophisticated cooling, contributes to impressive power handling and freedom from dynamic compression.
The B120’s proprietary woofer diaphragm is constructed of micro ceramic composite (MMC), a new material created by adonizing both sides of an aluminum core adds strength and stiffnews – but very little weight – to a material already well suited for use in transducer diaphragms. The B120 spider incorporates a superior-strength Nomex®/cotton blend with optimized geometry for increased linearity.

With an optional TX1 wireless transmitter connected to your audio system, the B120 can be placed anywhere in your room within reach of an AC outlet. One or two B120 subwoofers can be operated with a single TX1 transmitter.

The B120 cabinet is constructed of rigid MDF with extensive internal bracing to reduce cabinet-induced colorations. A downward-firing port allows for placement against a wall or in a cabinet. Rubber-padded feet ensure optimal stability on any floor surface.
