Deep, Powerful, Active Bass for Every Performance
That is exactly why we have created the T-Sub-AX series of active subwoofers.
The internal Class D amplifier delivers huge output power into the custom Wharfedale Pro LF driver to produce extreme subs and low end pressure into any system. Built for big bass, the plywood constructed cabinet is rock solid and is protected in durable black paint.
You’ll not only ‘feel’ a T-SUB-AX, but you will also see it! A new illuminated WP logo badge subtly glows and adds to the overall on-stage “power” of the new T-Sub.
T-Sub-AX models are designed to be the perfect companion for a Typhon or a Titan active loudspeaker.
Hold on to your socks! T-Sub-AX is going to blow them off!
