Compact performance

The WLA-28 has been developed to condense the extreme SPL and long-throw capabilities of the WLA-12 in to an all- new 2 x 8” configuration. The smaller configuration is no-less of a speaker, in fact the smaller configuration is what makes it so versatile – with the ability to dismantle your stack into smaller units, the compact addition to the WLA series is perfectly suited for rental companies and for many other portable PA applications where high power and high sound pressure in an array formation are essential. Of course, this is also well suited to fixed installation including theatres and concert halls.
Huge power potential
The WLA-28 uses a pair of high powered 8” LF drivers and a 3.2” neodymium HF driver to generate an impressive 132dB Max SPL and 1600W peak power. Arrays of up to 12 WLA-28 modules can be suspended using the WLA-28 Fly Frame, or up to 8 WLA-28 combined with a WLA-15B for maximum impact.
Extend your Bass
To extend the low end of your array, is the Wharfedale Pro WLA-15B Sub. Reaching depths of 35Hz and with an output potential of 2800 Watts peak it’s a perfect match for the WLA-28. The low end response applies itself to the most demanding music genres with the same long- throw capabilities of it’s smaller counterpart.
Rock solid

As with all Wharfedale Pro PA systems, years of expertise is behind a loudspeaker built to last, with thanks to our high standards of quality control. Both the WLA-15B and WLA-28 are coated in the high quality Rhino Rock paint finish – a texture with a professional, discrete aesthetic whilst being prepared for the rigours of life on the road.

DUAL 8"

At the heart of the WLA-28 is 2 x 8″ custom Wharfedale Pro LF drivers.

These feature 2.0″ voice coils to ensure high efficiency and high power handling.

The HF Compression driver is also custom made by Wharfedale Pro. Using a massive 3.2″ voice coil, this compression driver is coupled to a 100° x 10° waveguide.

These custom designed transducers are what give a WLA-28 system its incredible sound and power handling capacity.


OPTIONAL COMMON FLY FRAME

Arrays can be assembled using only WLA-28 line array elements or with WLA-15B / WLA-28SUB Subwoofers at the top of the array.

The WLA-28 Common Fly frame supports up to 12 x WLA-28 elements and a WLA-28SUB.
