    All Delta-AX models use premium Baltic birch plywood construction.

    Not only does this create a solid and durable cabinet, but it also contributes to the overall sound and character.

    Delta-AX is also covered in our most durable and hard wearing Rhino Rock paint finish. This ensures that a Delta-AX will always look as good as the day you unboxed it.


    Delta-AX features a routed Wharfedale Pro logo.

    This fresh design helps to distinguish between the original Delta-A models and the updated Delta-AX models.

    It is also a logo to be proud of. A logo that lets your audience know that the sound of your even will be of the highest possible quality.
