QSC Dual 18in Passive Subwoofer (Black) - GP218-sw-BK

The GP218-sw is a premium, high-performance, rectangular dual 18" subwoofer designed for ground stacked use in the most demanding touring or installed concert applications. With an impressive combination of punch, low-frequency extension and musical accuracy, the QSC GP218-SW-BK is an ideal companion for the acclaimed QSC WideLine series as well as other professional sound reinforcement systems. For suspension in permanent installations each GP218-sw QSC passive subwoofer comes with a total of sixteen (16) threaded M10 inserts (four per side).

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. An aluminum demodulating ring is employed for low distortion.

Like its "flyable" brother, the WL218-sw, the GP218-sw subwoofer's sonic performance and output capacity are second to none. But for those who only need the exceptional sonic performance, without the need for expensive rigging and flying capability - the GP218-sw gives the exact same sonic impact, but for a more economical price tag.
