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.
Premium Design Details
The B140 embodies luxury craftsmanship and decades of loudspeaker expertise, featuring magnetically attached grilles for a clean, seamless look with no visible fasteners. Hidden hardware and integrated trim rings add a refined touch, while a polished black accent complements the rigid, cross-braced cabinet. Solid aluminum feet with optional spikes and floor protectors ensure optimal positioning and isolation. Gently curved cabinet sides are finished in premium wood veneers, available in natural walnut or black walnut. Every detail is designed to please the eye as much as the ear.
Constant Pressure Gradient Rear Ported Cabinet
Revel’s patented Constant Pressure Gradient Port exemplifies precision engineering, delivering a uniform pressure change along its entire length. This innovative design minimizes turbulence and virtually eliminates port noise, ensuring pristine, distortion-free bass performance that complements the subwoofer’s uncompromising craftsmanship.
