T-SUB-AX18B is an 18″ active subwoofer from our T-SUB-AX Series — delivering deep, high-impact bass and exceptional power for live sound, DJ and installation environments.
Powered by a convection-cooled Class D amplifier, it delivers 900 W continuous and 1800 W peak power through a custom Wharfedale Pro 18″ quad-layer driver with a 3.0″ voice coil. The adjustable low-pass filter ensures seamless system tuning, making it an ideal low-frequency partner for Tourus, Titan and Typhon active tops.
Built from premium birch plywood and finished in our ultra-durable polyurea Tough-Tone paint, the T-SUB-AX18B features an illuminated front logo, integrated handles and a 35 mm pole socket for versatile setup. Designed for power, precision and reliability — it’s the subwoofer that truly shakes the stage.
