The legendary SB1000z is a high-performance, large-format subwoofer system with proven performance to complement high-efficiency, full-range speakers. It is designed for portable use where the thicker sound of the dual 18-inch drivers is desired. The SB1000z's driver mounting maximizes cone area and minimizes frontal area, providing the acoustic performance and physical configuration suitable for creating large subwoofer arrays. Applications include: concert touring, stadiums, band/club PA, large houses of worship, large auditoriums/theaters, stage/artist monitoring, drum fill monitoring, and large dance clubs.
