Dual 8"

Safely protected from the rain, are the all-important drivers.

Dual 8.0″ Wharfedale Pro LF drivers with 2.0″ voice coils deliver a smooth and powerful sound as expected from a WLA series array.

The HF compression driver uses a ferrite magnet and a 3.0″ voice coil to produce detailed HF without harshness, even at high volumes.

Optional FLY FRAME

Arrays can be assembled using only WLA-28F line array elements or with the WLA-28SUBF Subwoofers at the top of the array.

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

Optimised Ground Stacking

WLA-28F rigging doubles up as an optimised ground stacking system, using the WLA-28SUBF subwoofer as a base.

Arrays of WLA-28F line array elements can be aimed downwards by as much as 10° to cover audience areas close to a stage, as well as upward by as much as 10° in order to better cover distant balcony seating areas. 

IPX6

With the same reliability and high performance characteristics as the original ‘non-F’ models, these WLA-28 ‘F’ models are IPX6 Certified.

This certification states that there should be no harmful effects when “Water is projected in powerful jets (12.5mm nozzle) against the enclosure from any direction”

With rust-proof aluminium grilles, components wrapped in wax and anti-corrosion stainless and aluminium screws and hardware, the F models are made for the rain and long-term environmental exposure.

In addition, to reduce any risk of standing water, and to help rental companies with storage, the front grille has been flattened.

Optional TOUR BAGS

Protect your WLA array system with the WLA-28F and WLA-28SUBF tourbags.  Great for storage and protection during transportation.

Removable panels and front grille allow the WLA element to be used even while in its protective padded covering. Ideal for rental and touring applications, these tour bags will keep your system safe and protected during its hardworking lifespan!

 

AMPS & DSP

A Versadrive DSP (such as SC-48 FIR) or a DP-N series amplifier with internal FIR filtering is highly recommended to get the most from the system.  Phase, EQ and filtering should be applied and this way, the physics of the system can be truly optimised – delivering that sub-bass, power and clarity that this system can deliver.
