Ideal for live events, installations, and mobile sound systems, the Delta-AX18B offers a seamless integration with full-range speakers for a complete, high-quality sound experience.
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 black paint finish. This ensures that a Delta-AXF 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.
Full Range
The full range models (Delta-AX12 and Delta-AX15) use 2 x Class D amplifiers. These are specifically tuned and selected to be the perfect match for the HF and LF drivers inside.
With multiple analogue inputs, Delta-AX full range models are ready to connect to whatever signal source you have.
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.
