Wharfedale

Wharfedale Delta 15" 800w Active Speaker

Through both electronic and software optimisation, the new DELTA-AXF12 and AXF15 models now feature internal FIR filters using ‘DNA’ harvested from the flagship WLA active line array and monitors system development. This FIR filtering has brought independent control of magnitude and phase, more detailed equalisation and optimisation of frequency and power response. In the end….this results in highly improved system performance. The amplifiers have also been optimised, resulting in 800 W Continuous power.

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 retro-fitted by Service engineers. AXF models are also perfectly tuned to be used with the current DELTA-AX15B and DELTA-AX18B active subwoofers.

Specifications:

  • 15″ two-way bi-amplified active loudspeaker
  • 800 watts Continuous power
  • 1600 watts Peak power
  • 90° x 45° dispersion
  • 2″ HF Compression driver
  • 3″ LF voice coil
  • Advanced Internal FIR DSP 
  • 131.5 dB Max SPL @ 1 meter
