Description
The Wharfedale Pro Delta-AX15B is a high-performance 15-inch active subwoofer designed to deliver powerful and precise low-frequency reproduction. Built with premium Baltic birch plywood and finished with a durable black paint coating, it offers exceptional durability and a sleek, professional appearance. The Delta-AX15B is engineered to complement Delta-AXF full-range loudspeakers, creating a seamless and balanced sound system for live events, installations, or portable setups. Its robust construction, efficient amplification, and deep bass response make the Delta-AX15B the perfect choice for enhancing low-end impact in demanding audio applications.
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.
