Introduction - Wharfedale Pro WLA25SF User Manual

INTRODUCTION

Designed for the most demanding concert and installation audio professionals, the WLA-25 system sets new standards
for astonishing acoustical performance in a compact size.
Line arrays are increasingly employed in a wider range of venues and applications. Frequently these venues have height
or sightline restrictions that limit the placement and size of the array. Rising fuel costs are putting pressure on touring
system providers to downsize their transportation requirements. At the same time, client and audience expectations for
audio performance has never been higher. To meet these needs, Wharfedale Pro embarked on a program to develop the
most compact, highest output line array speaker system available.
Each WLA-25 element uses a pair of high-power, 5" low-frequency drivers. Both cover low frequencies while only one
extends into the mid range, thus maintaining horizontal dispersion control at a crossover. High frequencies are handled
by a premium 1.75" diaphragm, neodymium compression driver, 100° x 10° multiple aperture diffraction waveguide. This
creates a wide coverage with a superb stereo image and allows for more diverse placement.
The waveguide exit extends nearly to the top and bottom of the enclosure to create a continuous acoustical source with
minimal discontinuities between adjacent elements resulting in greatly reduced destructive interaction.
Premium materials are used throughout the system. The enclosure is constructed of Baltic birch plywood and coated
in an environmentally friendly, waterborne polymer finish that is field repairable. To keep the weight to a minimum and
prevent rust, suspension fittings are made of aluminium.
An elegantly simple 3-point suspension system combined with light weight, compact size and excellent handling
ergonomics mean that a one person crew can easily deploy an array. With a choice of 3 different fly frame options
suspension is easy, tidy and safe. The WLA-25 system is equally at home in the air or ground-stacked.
