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 SB250zR is a high output, mid-size subwoofer system. This
versatile, all-purpose subwoofer is designed for portable use
where the solid-sounding output of dual 15 inch drivers is
desired. The SB250zR works well with most full-range
loudspeakers in a variety of applications including: band/club
PA, 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 SB250zR 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.
