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.
We recommend using SC48FIR DSP with the Line Array.
