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 SB528zR is a high output, large-format subwoofer system.
This versatile, all-purpose subwoofer is designed for portable
use where the fatter-sounding output of dual 18 inch drivers is
desired. The SB528zR works well with most full-range
loudspeakers in a variety of applications including: band/club
PA, large houses of worship, large auditoriums/theaters, arenas,
concert touring, f/x reinforcement, large dance clubs, and drum-
fill monitoring.
The SB528zR 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.
1 To achieve specified performance, the listed external signal processing with EAW-provided settings is required.
2 For recommendations to select power amplifier size refer to : "HOW MUCH AMPLIFIER POWER DO I NEED?" on the EAW web site.
EAW products are continually improved. All specifications are therefore subject to change without notice.
