Wharfedale Pro WLA-218BXF - IPX6 waterproof line array subwoofer
WLA-218BXF is a dual 18″ IPX6-rated subwoofer from our WLA-28XF System, engineered for outdoor events and permanent installations demanding extreme low-frequency power and full weather protection.
Based on the proven WLA-218B design, this waterproof “F” model retains the same high-output performance while ensuring complete resistance to rain and moisture. Rust-proof aluminium grilles, wax-coated components and stainless-steel hardware provide long-term environmental durability, while the flat front grille prevents standing water and improves handling during storage.
Constructed from 18 mm birch plywood, WLA-218BXF features dual custom Wharfedale Pro 18″ drivers and a single WY-24K4Z waterproof input connector, delivering a maximum SPL of 148 dB @ 1 m with deep, controlled sub-bass power.
Built for reliability in all weather conditions, WLA-218BXF extends the WLA-28XF system with commanding, waterproof low-end reinforcement.
