Description
The Wharfedale Pro WLA-28SUBA is a powerful active subwoofer designed to complement the WLA-28X line array system, offering enhanced low-frequency performance for large-scale professional audio applications. Featuring dual 15-inch high-efficiency drivers and built-in amplification, the WLA-28SUBA delivers deep, punchy bass with impressive power handling. Its rugged birch plywood enclosure is built for durability, ensuring reliable performance in challenging environments. The integrated Class D amplification is optimized for the subwoofer's drivers, providing consistent and distortion-free bass reproduction. Ideal for live events, touring, and installations, the WLA-28SUBA seamlessly integrates with other Wharfedale Pro components to provide an immersive and balanced sound experience with outstanding low-end reinforcement.
Internal DSP with Fir
8 x DSP Presets – built in – including FIR. Easy to get great results – fast. For the subwoofers (WLA-28SUBA and WLA-218BA) the AUDIENCE or STAGE presets can be used in an Inverted Stack Gradient array configuration.
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.
Dual 8"
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 450 kg. Thats 12 x WLA-28X elements and a WLA-28SUB.

Optimised Ground Stacking
WLA-28X rigging doubles up as an optimised 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.
Wheely Useful
With the WLA-28 Dolly Frame, manoeuvrability is now an added feature. The steel frame acts both as a common fly frame for flying situations AND as a dolly for ground stacking. 3 outriggers add stability to a ground stack allowing up to a maximum of 1 x WLA-28SUB plus 4 x WLA-28X’s to be configured. Adding extra versatility to any WLA-28X system.
