KEY FEATURES
- Internal FIR signal processing
- Proven ‘DELTA Active’ reliability
- Practical ‘DELTA Active’ design
- Retro-fittable electronics
- Compatible with DELTA active subwoofers
- Increased Continuous Power. Now 800 Watts
DESCRIPTION
The new DELTA-AXF models have the same solid Baltic birch plywood construction and the same custom-made Wharfedale Pro
drivers as their predecessors, but with the new FIR filters, the sonic improvements are clear. The updated ‘AXF’ electronics are
fully interchangeable with existing DELTA active models and can be quickly retrofitted by Service engineers. AXF models are also
perfectly tuned to be used with the current DELTA-AX15B and DELTA-AX18B active subwoofers.
