QSC GP118-sw 18" Passive Subwoofer (Discontinued)

The QSC GP118-sw is a powerful subwoofer that offers plenty of “punch” while maintaining ample extension so the musically important fundamentals are solidly and accurately reproduced. With an impressive combination of low-frequency extension and musical accuracy, 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-inch 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 extensively vented to reduce power compression. An aluminum demodulating ring is employed to further 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. It is available in a black or white finish.
