Dual 18″
The two 18” Wharfedale Pro LF transducers with massive 4” voice coils work together to deliver up to 148dB Max SPL.Using cast frame aluminium baskets, any mechnical distortion is dramatically reduced ensuring smooth, accurate and honest reproduction.

Huge voice coils
The 4″ voice coils ensures massive power handling.The WLA-218B can handle peaks of up to 8000w and programme material averaging 4000w.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-218B has been carefully designed to avoid any vibrations or shape distortions during high volume use.Using 18mm plywood the cabinet is ready for whatever the bottom-end needs.
