QSC WL118-sw Installation Subwoofer
The WL118-sw is the subwoofer partner for QSC's WL2082-i installation line array, a single 18 inch driver in a vented bass-reflex enclosure that reaches down to 29 Hz with 850 watts of continuous power capacity. It shares the WL2082-i's molded, weather-resistant construction so a mixed rig looks and finishes the same throughout.
The sub can be suspended at the top of a WL2082-i array using the standard array frame, or flown behind the array with the optional extension bar when trim height is limited, and it doubles as a ground-stack base for the array elements.
