About the Reference 8b

The KEF Reference 8b subwoofer features a force-cancelled closed-box design with two 225mm (9-inch) long-throw, ultra-low distortion drivers mounted back-to-back in a heavily braced, acoustically inert cabinet. It employs dual 500W Class D amplifiers (1000W total) with switched-mode power supply and DSP-based control for powerful, accurate bass reproduction with effortless body and weight. Ideal for high-fidelity systems, it delivers exceptional precision and control with zero distortion, supporting both music and home theater applications. Note: This model is no longer in production but may be available from remaining stock.
