Product Description

An 18" sub with 1000 Class D continuous output, and extended bass in a lighter birch enclosure.

Building on the success of QSC's K Series, the KW181 subwoofer, like the rest of QSC's KW active loudspeakers, represents QSC's next evolutionary step in wood enclosure loudspeakers. The system engineers created the KW series to feature all the groundbreaking electronic attributes of the popular K Series while at the same time designing a product that is both smaller and significantly lighter than previous wood enclosure models.

High Output
Like it K series predecessors, the QSC KW181 speaker features a QSC designed, 1000W (2 x 500) Class D power module. The loudspeaker is also fitted with an 18" cone transducer of the same high-quality design.
