[. . . ] 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. The B120 subwoofer delivers accurate and authoritative bass from a surprisingly compact enclosure. [. . . ] Backed by the extensive facilities and resources of Harman International, Revel products benefit from cutting-edge development tools unavailable to most manufacturers, such as: ·A multichannel listening lab, facilitating double-blind listening tests ·A laser interferometer, enabling detailed driver and cabinet analysis ·Multiple large anechoic chambers, providing precise tests and measurements ·Finite-element analysis, allowing for advanced loudspeaker modeling ·Stereo lithography equipment, aiding in the achievement of tight tolerances B120 Powered Subwoofer Deep, Realistic Revel® Bass ­ Wired or Wireless.

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). To tame the subwoofer's response in the listening room, the B120 features a parametric room EQ function, with controls for frequency, level and bandwidth to tune out room-induced response anomalies.
