WLA-25 is a two-way passive line array system which features the same design philosophy as its established larger brother, the WLA-28.
It brings long throw capabilities together with extreme SPL – all from within a compact and portable array system.

The biggest breakthrough during the development process was the creation of a custom Wharfedale Pro neodymium HF compression driver. This newly engineered HF component delivers extreme sensitivity from a very compact and lightweight design. Along with its supersensitive 1.75” voice coil, this HF compression driver also features aluminium back plating which acts as a heat sink to aid heat dissipation. This attention to detail protects the driver from heat damage and mechanical distortion during extreme performance levels.

The 2 x 5” custom LF drivers have been developed to work in partnership with this neo HF driver. Rigid die cast baskets ensure consistent sonic performance with minimum distortion. The placement and physical mounting of all the drivers have been fine tuned to ensure maximum phase coherence and SPL are achieved from the compact cabinet.

The specially designed acoustic grilles in front of the 5” woofers optimise the midrange directivity while the HF exponential horn delivers consistent HF accuracy and detail. In addition, the trapezoidal enclosure has been developed to reduce any acoustic sidelobes within the array.

For low-end punch we have also created the 141 dB SPL WLA-25SUB subwoofer. This subwoofer physically and acoustically matches the WLA-25 system. Using a reversed-phase horn loaded design, the 2 * 10” LF drivers with massive 2.5” coils deliver the consistent low end punch to complete this versatile array.

The hardware design allows the system to be groundstacked or it can be flown using the matching WLA-25 Flyframe or WLA-25SUB Flyframe.

Available in a black or white Rhino Rock covering, the compact WLA-25 and WLA-25SUB is a perfect system for multi-function halls, theatres, and houses of worship.

WLA-25 Fly Frame

  • Arrays can be assembled using only WLA-25 line array modules. 
  • The smaller WLA-25 Fly Frame supports up to 12 x WLA-25 elements with a safety factor of 12.

WLA-25SUB FLY FRAME

  • Arrays can be assembled using only WLA-25 line array elements or with WLA-25SUB Subwoofers at the top of the array. The WLA-25SUB Fly Frame allows for a WLA-25SUB subwoofer to be used at the top of the array. It supports up to 12 x WLA-25 elements and 1 x WLA-25SUB with a safety factor of 12.

WLA-25 Common fly frame

  • The WLA-25 Common Fly Frame allows for either WLA-25 elements or WLA-25SUB elements to be flown.  A versatile fly frame for any occasion.

Dual 5"

At the heart of the WLA-25 is 2 x 5″ custom Wharfedale Pro LF drivers.

These feature 2.5″ voice coils to ensure high efficiency and high power handling.

The HF Compression driver is also custom made by Wharfedale Pro. Using a Neodymium magnet and a 1.75″ voice coil, this compression driver is coupled to a 100° x 10° waveguide.

These custom designed transducers are what give a WLA-25 system its incredible sound and power handling capacity.

Just imagine

Imagine your dream system!  You can configure a WLA series rig to suit your needs!

To help your design and system preparations, you can download some recommended system diagrams.  These range from small to large and use a selection of our different amplifier ranges. 

WLA-25 Stand frame

The optional WLA-25 Stand Frame makes a WLA-25 system even more portable and versatile.  Use the WLA-25SUB MKII which features an M20 screw pole mount.

Optimised Ground Stacking

WLA-25 rigging doubles up as an optimised ground stacking system, using the WLA-25SUB subwoofer as a base.

Arrays of WLA-25 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. 

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.
