Used in a church for several years, selling because we upgraded equipment.

The SB180zR is a high output, mid-size subwoofer system. This versatile, all-purpose subwoofer is designed for portable use where the fatter-sounding output of an 18 inch driver is desired. The SB180zR works well with most full-range loudspeakers in a variety of applications including: band/club PA, small houses of worship, small auditoriums/theaters, A/V systems, hotel ballrooms, meeting rooms, classrooms, exhibit areas, f/x reinforcement, cruise ships, small dance clubs, DJ monitoring, and drum-fill monitoring. 

The SB180zR is designed to be used with today's sophisticated digital signal processing to optimize the LF response. EAW's MX Series processors are recommended for the required crossover and equalization.
