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.
