DESCRIPTION

The SB products are EAW's premium subwoofers 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 SB528zP is a high output, large-format subwoofer system. This versatile, all-purpose subwoofer is designed for permanent installation where the fatter-sounding output of dual 18 inch drivers is desired. The SB528zP works well with most full-range loudspeakers in a variety of applications including: large houses of worship, large auditoriums/theaters, f/x reinforcement, cinemas, and large dance clubs.

The SB528zP 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.

Six Year Warranty.
