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.
