Description

About QSC GP218-sw Dual 18inch Passive Subwoofer

The GP218-sw is a premium, highperformance, direct radiating dual 18-inch subwoofer designed for use in portable and installed sound applications. This powerful subwoofer 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 GP218-sw is an ideal companion to QSC’s WideLine Series, ILA Series, AcousticPerformance™ Series and AcousticDesign™ Series loudspeakers.

The GP218-sw features two 18-inch transducers that incorporate a double layer spider and triple roll surround for extended and controlled excursion at extreme power. The 4-inch voicecoil 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 QSC GP218-sw dual 18inch passive subwoofer 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.

Further contributions to cabinet rigidity include vent walls constructed of the same plywood as the enclosure. Ample port area allows free movement of air resulting in minimal turbulence and port distortion. Finishing the enclosure’s aesthetic design, the transducer is protected by a 16-gauge, powder coated steel grille.

To aid in transporting the QSC GP218-sw dual 18inch passive subwoofer, the unit features built-in handles with options for a dolly board and soft cover. For increased versatility, the GP218-sw can be stacked vertically using their interlocking feet and recess features machined into the enclosure’s top panel.
