For high-level dance music or reinforcement of bass instruments and kick drum, a KW series subwoofer will add low frequency extension and power to any sound system. The KW181 subwoofer represents QSC's next evolutionary step in wood enclosure subwoofers. The loudspeaker is fitted with an 18" cone transducer, and features a QSC designed, 1000W (2 x 500) Class D power module. Extensive signal processing is employed throughout, providing levels of sonic clarity and total output that defy all expectations for a speaker in this category.
