DESCRIPTION

The SB products are EAW's premium subwoofers designed for
the most demanding professional applications. Abroad 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 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 P A, 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.
