Everyone Loves BAss !

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!


T-Sub-AX models have been designed to be the perfect partner for Wharfedale Pro plastic active loudspeakers.

Used with a Tourus, a Titan or our flagship Typhon models, a T-Sub-AX completes the system – bringing new levels of bass to the setup.

Protect the bass

Protective optional soft covers are available for all T-Sub-AX Active Subwoofers.

With easy access to both carry handles and a soft protective padding, the T-Sub soft covers are simple to put on and simple to remove – making setup and breakdown easy.
