Dual 18" Subwoofer 1700-watt
The QSC WL218-sw is a premium, high-performance, dual 18" subwoofer designed for suspended or ground stacked use in the most demanding touring or installed concert applications. With an impressive combination of punch, low-frequency extension and accuracy, the WL218-sw is an ideal companion for QSC's acclaimed WideLine as well as other professional sound reinforcement systems.
Sound system designers and operators are increasingly turning to subwoofer systems that are flown with the main array for a more seamless acoustical transition from the bass to the low-mid region. With a simple, three-point suspension design that is essentially a scaled up version of the QSC WideLine system, the WL218-sw fulfills the requirement while also delivering powerful and stunningly accurate low frequency output.
Suspension of the array requires one AF218-sw 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.
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 extensively vented to reduce power compression. An aluminum demodulating ring is employed for low distortion.
