The WL218-sw and the GP218-sw are premium, high-
performance dual 18" subwoofers designed for use in
the most demanding touring or installed concert
applications. They are acoustically identical subwoofers,
differing primarily in suspension hardware.
With an impressive combination of punch, low-
frequency extension and musical accuracy, these
subwoofers are ideal companions for the acclaimed QSC
WideLine™ Series 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
extensively vented to reduce power compression. Both
enclosures are constructed of premium quality birch
plywood with extensive internal bracing and finished to
stand up to heavy use.
WL218-sw
The WL218-sw can be flown or ground stacked. Using
the AF218-sw array frame, up to eight WL218-sw

factor. The subwoofers may be stacked vertically using
the interlocking feet and recess features. For ease of
transport, the WL218-sw includes a caster pallet with
rugged 3.5" ball bearing casters and an easy-to-use,
snap-on mechanism for attachment to the enclosure.
GP218-sw
The GP218-sw omits the WL218-sw suspension
hardware and trapezoidal shape but retains all the
acoustical performance of the WL218-sw at a lower
cost. For ground-supported applications, the
subwoofers may be stacked horizontally using their
interlocking feet and recess features machined into
the enclosure’s top panel. For suspension in
permanent installations each GP218-sw subwoofer
includes a total of sixteen (16) threaded M10 inserts.
An optional transport caster pallet is available.
