BIRCH PLYWOOD
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.
ROUTED LOGO
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.
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.
Using convection cooling, Delta-AX models do not use any internal fans. Fans add to product weight, ambient noise and can lead to unreliability. Delta-AX has no fans!
The amplifier has been perfectly matched to the custom low frequency driver. This perfect combination leads to maximum efficiency and supreme output SPL.
