Eastern Acoustic Works' SB180ZP premium subwoofer is designed for the most demanding professional applications. A broad range of capabilities and sizes provide the designer with selections that can be specifically matched to their application. Top quality drivers, engineered by EAW, provide the highest output and best sonic performance possible for a given form factor. All SB models are direct radiating, with optimally tuned, vented enclosures. SB subwoofers are the choice where the best sonic performance, highest reliability, and most robust physical construction are required. The SB180zP is a high output, mid-size subwoofer system. This versatile, all-purpose subwoofer is designed for permanent installation where the fatter-sounding output of an 18 inch driver is desired. The SB180zP works well with most full-range loudspeakers in a variety of applications including: small houses of worship, small auditoriums/theaters, A/V systems, hotel ballrooms, meeting rooms, classrooms, exhibit areas, f/x reinforcement, cruise ships, cinemas, and small dance clubs. The SB180zP 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.
