ABOUT THE CLARITY
The new neo HF compression driver delivers additional clarity and performance with enhanced definition. It is custom made by Wharfedale Pro and is coupled to a 100° x 10° waveguide.
At the heart of the WLA-28X are 2 x 8″ custom Wharfedale Pro LF drivers.
These feature 2.0″ voice coils to ensure high efficiency and high power handling.
These custom designed transducers are what give a WLA-28X system its incredible sound and power handling capacity.
OPTIONAL FLY FRAMES
Arrays can be assembled using only WLA-28X line array elements or with WLA-15B / WLA-28SUB Subwoofers at the top of the array.
The WLA-28X Common Fly frame supports up to 12 x WLA-28X elements and a WLA-28SUB.
COMPARE WLA-28X TO THE ORIGINAL WLA-28
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.
OPTIMISED GROUND STACKING
WLA-28X rigging doubles up as an optimized ground stacking system, using the WLA-15B or WLA-28SUB subwoofer as a base.
Arrays of WLA-28X 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.
BI-AMP & PASSIVE
In BI-AMP mode, two power amplifiers can be used. This gives you the advantage of being able to select the best power amplifier specifications for each driver inside the loudspeaker. In a BI-AMP configuration, an external crossover is used to separate the frequencies and this splits the signal to the dedicated LF amplifier and the HF amplifier. This way, each amplifier is only working on the given frequency range and, in turn, is powering the corresponding driver inside the loudspeaker.
In PASSIVE mode, a single amplifier can be used to power all drivers inside the loudspeaker. The full frequency range is put into the loudspeaker and the loudspeakers’ internal crossover separates the frequencies, delivering the right frequencies to the right driver. In the example of a 2-way passive loudspeaker, this means that the single amplifier is powering both the HF compression driver and the LF transducer. The internal crossover takes care of both the frequency and power separation.
AMPS & DSP
A Versadrive DSP (such as SC-48 FIR) or a DP-N or DP-F 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.
