To experience the full impact of dramatic on-screen effects, bass definition and control are as important as extension. For power with accuracy, the Reference sub boasts two 500W Class D amps, each driving a 228mm (9 inch) long-throw, ultra-low distortion driver, connected back-to-back in the heavily braced, acoustically inert cabinet. Only a truly great subwoofer could do justice to Reference standards of home theatre, and it does.
