The Heartbeat of the Performa Experience
Are you looking to bring depth, weight, and cinematic impact to your home entertainment system? With the Revel Performa4 B140 as the heartbeat of your setup, you’ll achieve the room-shaking bass you’ve been craving. This 10-inch powered subwoofer houses a robust 750-watt RMS amplifier, matched to a fiber-composite cone woofer in a cast-aluminum frame. This design not only ensures optimal stiffness and reduced weight, which enhance driver efficiency, but it also offers superior damping to minimize unwanted resonances. It’s bolstered by inverted surrounds, maximizing surface area and air movement, and topped off with an eye-catching trim ring cover. Moreover, these components work in tandem with a bass-reflex, rear-ported enclosure, delivering low-frequency authority that completes any Revel loudspeaker system. Beyond that, the B140 includes a bevy of tuning options, comprising Volume, Crossover, and Phase controls, along with ample connectivity for streamlined integration into any setup. Meticulously tuned using rigorous double-blind, position-independent testing, utilizing cutting-edge psychoacoustic research and processes, the B140 provides you with accurate, high-fidelity bass reproduction with few rivals.
