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 WHARFEDALE PRO 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.
CLASS D AMPLIFICATION
Inside the DELTA-AX15B 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 15" low frequency driver. This perfect combination leads to maximum efficiency and supreme output SPL.
