Description
Born from decades of world-class loudspeaker innovation, the Revel B140 powered subwoofer is the perfect companion to the Performa4 floorstanding and bookshelf loudspeakers. It features a 10-inch (250mm) fiber-composite cone woofer mated with a 750 Watt digital amplifier and includes a host of connectivity and tuning options to integrate seamlessly into any system. These components work in harmony with a bass-reflex tuned port enclosure to achieve unmatched audio accuracy and powerful deep bass response that makes your music and movies come alive.
Fiber-Composite cone low-frequency driver
The B140 features a robust 10-inch (250mm) coated fiber-composite cone woofer designed around a precision cast aluminum frame. At its core is a massive 3-inch (75mm) two-layer copper voice coil, delivering an impressive 1.25-inch (30mm) peak-to-peak excursion for exceptional low-frequency performance. To maintain linearity across this extreme excursion, the pole piece extends 0.25-inch (10mm) above the top plate, ensuring a stable magnetic field. This extension also serves a dual purpose by enhancing thermal dissipation, keeping the voice coil cool under demanding conditions.
High-Power Class D Amplification
The B140 is powered by a high-efficiency Class-D amplifier delivering an impressive 750 watts RMS and 1,500 watts peak, ensuring deep, powerful bass response down to 26 Hz.
Rear-Mounted Volume, Crossover, Phase, and Power Controls
The B140 offers a comprehensive set of rear-mounted controls for precise system integration: Variable Low-Pass Filter (50–150 Hz) – Allows perfect adjustment to match your main speakers. LFE Input – Bypasses the low-pass filter when connected to a receiver or processor with its own bass management. Phase Control – Variable adjustment for seamless blending with your system. Volume Control – Fine-tunes output for perfect balance. Auto On/Off – Automatically powers the subwoofer on when a signal is detected and off when idle, saving energy.
