The GP118-sw 18" Portable Subwoofer from QSC is a high performance, direct radiating 18" subwoofer with a black tour grade finish. It is designed for use in portable and installed sound applications. The GP118-sw is an ideal companion to QSC's WideLine Series, ILA Series, AcousticPerformance Series and AcousticDesign Series loudspeakers. The GP118-sw features an 18" transducer that incorporates 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 to reduce distortion.

The GP118-sw is housed in an 18mm Baltic birch plywood enclosure and finished in an environmentally friendly, waterborne, polymer finish rugged enough for the demands of everyday use while also being field repairable. Internal bracing is employed to eliminate acoustic losses due to panel resonance while maintaining the enclosure's robustness. The vent walls are constructed of plywood, and the ample port area allows free movement of air. The transducer is protected by a 16-gauge, powder coated steel grille. The GP118-sw includes built-in handles for ease of transport. For increased versatility, the subwoofer can be stacked vertically using the interlocking feet and recess features machined into the enclosure's top panel. The GP118-sw can also be reversed to facilitate cardioid array deployment.
