WLA-118SUB is an 18″ subwoofer from our WLA-1 System, engineered to deliver deep, controlled low-end extension for touring and installation applications demanding serious power and precision.
At its heart is an 18″ Beyma driver featuring a 4.0″ Duo In/Out LF driver voice coil, providing exceptional control, efficiency and durability under extreme load. Handling 1600 W continuous (up to 6400 W peak), the WLA-118SUB delivers a maximum SPL of 141 dB @ 1 m — powerful enough for large-scale events while maintaining accuracy and musicality.
Whether deployed as part of a flown array or as a ground-stacked configuration, it integrates seamlessly with WLA-1 full-range elements. The result is tight, punchy low-frequency reproduction with remarkable definition — a true low-end foundation for professional sound reinforcement.
