BIRCH PLYWOOD

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

ROUTED LOGO

Delta-AXF features a routed Wharfedale Pro logo.

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.
