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 SB120zR is a high output, compact subwoofer system. This
versatile, all-purpose subwoofer is designed for portable use
where the physically small size and the impact of a 12 inch driver
is desired. While the SB120zR works well with most full-range
loudspeakers, its most frequent uses are in high quality multi-
media systems. These applications include: A/V systems,
corporate events, meeting rooms, classrooms, exhibit areas, f/x
reinforcement, and cruise ships.
The SB120zR 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.
