The QSC WL218-sw is a large-format flying subwoofer built to add deep, high-output low frequency to the WideLine line array system and to demanding touring or installed rigs. It loads two 18-inch long-excursion drivers with 4-inch voice coils into a braced, vented trapezoidal enclosure of Baltic birch plywood, delivering extended, articulate bass for concerts, houses of worship, and large venues.
