Using a dual chamber cabinet, the WLA-218SUB delivers huge bass in a versatile configuration.
2 x 18” Wharfedale Pro LF transducers with massive 4” voice coils produce up to 138 dB SPL – while their cast frame aluminium baskets reduce any risk of mechanical distortion.
The WLA-218SUB cabinet is constructed of 18mm birch plywood and all internal bracing is designed to avoid vibration or physical shape distortion during prolonged high volume use.
This massive subwoofer is designed for ground placement.
4.0″ voice coils
18 mm Baltic Birch plywood construction
1600 W Continuous (Parallel)
3200 W Programme (Parallel)
6400 W Peak (Parallel)
138 dB Max SPL @ 1 meter
The two 18” Wharfedale Pro LF transducers with massive 4” voice coils work together to deliver up to 138 dB Max SPL.
Using cast frame aluminium baskets, any mechanical distortion is dramatically reduced ensuring smooth, accurate and honest reproduction.
WLA-218SUB is constructed of 18 mm thick Baltic birch plywood.
Not only does this create a solid and durable cabinet, but it also contributes to the overall sound and character.
WLA-218SUB is also covered in our most durable and hard wearing Rhino Rock paint finish. This ensures that it will always look as good as the day you unboxed it.
Parallel / discrete
Run the WLA-218SUB in Parallel or Discrete mode.
In Parallel mode both drivers are connected in parallel, resulting in a 4Ω subwoofer.
In Discrete mode both drivers operate individually and can respond to separate source material. In this configuration each driver is 8Ω.
SOlid as a rock
As with all Wharfedale Pro PA systems, years of expertise is behind a loudspeaker built to last, with thanks to our high standards of quality control.
The WLA-218SUB is coated in the highest quality Rhino Rock paint finish – a chip resistant texture with a professional, discrete aesthetic whilst being prepared for the rigours of life on the road.
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 ……directly into the faces of the audience!
For easy transportation, WLA-218SUB is compatible with Wharfedale Pro optional caster wheels.
