User manual REVEL B120 BROCHURE

[. . . ] T he Revel® ConcertaTM 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. [. . . ] Anodizing both sides of an aluminum core adds strength and stiffness ­ 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. The large ceramic magnet motor system includes a 2" (51mm)- diameter copper voice coil wound on a Kapton® bobbin for impressive power handling and freedom from dynamic compression. A vented center pole facilitates heat dissipation, allowing more efficient cooling for high-power handling and low compression. Built-In Wireless Receiver 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.

Certain low-bass frequencies may be adversely affected by standing waves (also known as room modes), where some frequencies are exaggerated (peaks), while others might be diminished (dips).
