The Wharfedale Pro T-SUB-AX12B Active Subwoofer is a 12″ active subwoofer from our T-SUB-AX Series — delivering powerful, punchy low-end reinforcement in a compact, durable design. Powered by a convection-cooled Class D amplifier, it delivers 500 W continuous and 1000 W peak output through a custom Wharfedale Pro quad-layer 12″ driver with a 2.0″ voice coil. The adjustable low-pass filter allows quick system tuning, making it an ideal companion for active tops such as the Tourus, Titan and Typhon series. Constructed from premium birch plywood and finished in our rugged polyurea Tough-Tone paint, the T-SUB-AX12B features an illuminated front logo, integrated handles and a 35 mm pole socket for flexible setup. Compact, reliable and ready to perform — it’s small in size but huge in sound.
