QSC WL218-sw WideLine Portable Subwoofer (White)

The WL218-sw WideLine Portable Subwoofer from QSC is a high-performance dual 18″ subwoofer with a white tour-grade finish. It is designed for suspended or ground stacked use in touring or installed concert applications, and can be used with the WideLine as well as other professional sound reinforcement systems. The 18″ woofers incorporate a double layer spider and triple roll surround for extended and controlled excursion at extreme power. The 4″ voice coil is wound on a fiberglass former to prevent deformation at high operating temperatures and is vented to reduce power compression. An aluminum demodulating ring is employed for low distortion. MFR # WL218-SW-TG

The enclosure of the WL218-sw is constructed of birch plywood finished in an environmentally friendly, waterborne, polymer finish that stands up to life on the road while also being field repairable. Extensive internal bracing is employed to eliminate acoustic losses due to panel resonance. Further contributions to cabinet rigidity come from vent walls constructed of the same plywood as the enclosure. Each woofer is protected by a heavy duty, 14 gauge, powder coated steel grille and housed in its own, separate chamber to prevent failure of one driver from causing damage to the other. Ample port area allows massive amounts of air to move freely, and the ports are arranged so as to eliminate asymmetrical loading of the woofers, which can result in distortion and voice coil failure related to rocking-modes.

The unit features 12 handles for ease for transport and handling. The included dolly has rugged, 3.5″, ball bearing casters and an easy-to-use, snap on mechanism for attachment to the enclosure. Suspension of the array requires one AF218-sw (sold separately) for each subwoofer array. The AF218-sw is a simple, heavy-duty array frame constructed of welded, aviation-grade 6061-T6 aluminum and intended for suspension of up to eight WL218-sw subwoofers with a 10:1 design factor. For ground-supported applications, the subwoofers may be stacked using the interlocking feet and recess features machined into the enclosure’s end caps. QSControl.net/BASIS DSP files are available for download. They are tuned for use with WL218-sw to provide optimized performance.
