Wharfedale Pro WLA-28A - 2 x 8" active element.
WLA-28A
WLA-28A - 2 x 8" active element. Birch plywood construction. Internal DSP with FIR filters. Software control over RS485 protocol.
DUAL 8"
At the heart of the WLA-28A are 2 x 8″ custom Wharfedale Pro LF drivers.
These feature 2.0″ voice coils to ensure high efficiency and high power handling.
These perfectly matched custom transducers are what give a WLA-28A system that special sonic impact.
INTERNAL DSP WITH FIR
8 x DSP Presets – built in – including FIR.
Easy to get great results – fast.
For the subwoofers (WLA-28SUBA and WLA-218BA) the AUDIENCE or STAGE presets can be used in an Inverted Stack Gradient array configuration.
ABOUT THE CLARITY
The new neo HF compression driver delivers additional clarity and performance with enhanced definition.
It is custom made by Wharfedale Pro and is coupled to a 100° x 10° waveguide.
SOFTWARE CONTROL
The network connection uses RS485 protocol and gives GUI control over the DSP parameters of each element in the array.
