WLA-218SUB

Sub-bass you will remember.

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 138dB 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.

Dual chamber, dual 18"
The two 18” Wharfedale Pro LF transducers with massive 4” voice coils work together to deliver up to 138dB Max SPL.

Using cast frame aluminium baskets, any mechanical distortion is dramatically reduced ensuring smooth, accurate and honest reproduction.
Parallel and 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
Huge voice coils
The 4" voice coils ensures massive power handling.

The WLA-218SUB can handle peaks of up to 6400w and programme material averaging 3200w.

These custom Wharfedale Pro drivers are efficient and powerful - delivering the sub-bass punch needed for larger gigs and impressive installations.
Strong internal bracing
With so much potential air movement, the cabinet of a subwoofer this size must also be incredibly robust - both externally and internally.

The internal bracing of the WLA-218SUB has been carefully designed to avoid any vibrations or shape distortions during high volume use.

The dual chambers allow each driver to work efficiently within their own space - reducing internal interference from each other.

Using 18mm plywood the robust cabinet is ready for whatever the bottom-end needs.
