DESCRIPTION
We just can’t help making things better. We are always looking for improvements that can be made. Our R&D team cannot stop taking everything that they see to pieces. They try different components, they update algorithms and they explore different physical system configurations. Dismantling…..measuring….testing….measuring……but then a break through comes.
Their work has now unlocked the true potential of the DELTA Active full range models which have been a trusted and reliable audio solution since their introduction in 2014.
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.
