The QW® 218 incorporates two of the new extra-high power Neoddium 18″ woofers and a new compact cabinet design. The QW 218 is a direct radiator subwoofer designed specifically for the high-end pro audio user.
The Low Rider 18″ driver is a milestone in high-power subwoofer design. An incredible 4600Watts program rating and extra-long cone excursion come together to produce amazing new levels of clean, deep bass. This makes the QW 218 a superior choice for the bottom end of any high powered sound system.
