The WL218-sw is a dual 18-inch (457mm) passive subwoofer designed for suspended or ground stacked use in touring or installed concert applications.

With an impressive combination of sonic impact, low-frequency extension, and accuracy, the WL218-sw is an ideal companion for QSC's WideLine as well as other professional sound reinforcement systems.

Suspension of WL218-sw subwoofers is easy using the AF218-sw, a heavy-duty array frame constructed of welded 6061-T6 aluminium. In ground-supported applications, the WL218-sw may be stacked using the interlocking feet and recess features machined into the enclosure's ends. 

Transport and handling features are also provided in the WL218-sw's design. No matter how the box is deployed, one of the dozen handles will be where it needs to be. The included dolly has rugged, 3.5-inch ball bearing casters and an easy-to-use, snap-on mechanism for attachment to the enclosure.
