BIRCH PLYWOOD

Delta-AX subwoofers 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 subs are 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.

ROUTED LOGO

Delta-AX subs feature 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.

SUBWOOFERS

The 15″ and 18″ active subwoofers use a single Class D amplifier to drive the LF transducer.

Inside the Delta-AX subwoofers is a highly efficient Class D amplifier.

The amplifier has been perfectly matched to the custom low frequency driver. This perfect combination leads to maximum efficiency and supreme output SPL.
