The GP218-SW Dual 18" Subwoofer from QSC is a high performance, rectangular dual 18" subwoofer with a black tour grade finish. It is designed for ground stacked use in touring or installed concert applications. The GP218-sw is an ideal companion for the 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. The 4" voice coil is wound on a fiberglass former designed to prevent deformation at high operating temperatures and is vented to reduce power compression. An aluminum demodulating ring is employed for low distortion. The enclosure of the GP218-sw is constructed of birch plywood finished in an environmentally friendly, waterborne, polymer finish that is 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. Woofers are protected by a heavy-duty, 14 gauge, powder coated steel grille and housed in separate chambers 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. For suspension in permanent installations each GP218-sw subwoofer comes with a total of 16 threaded M10 inserts (four per side). For ground-supported applications, the subwoofers may be stacked horizontally using their interlocking feet and recess features machined into the enclosure's top panel. QSControl.net/ BASIS DSP performance optimization files are available for download on the QSC website.

Four handles for transport and handling
