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 SB48zP is a highly compact subwoofer system optimized
for permanent installation. Its small size allows placement in tight
places while providing the extremely low frequency response of
much larger systems. While the SB48zP works well with most
full-range loudspeakers, its most frequent uses are in high
quality multi-media systems. These applications include: A/V
systems, meeting rooms, classrooms, exhibit areas, f/x
reinforcement, cruise ships, TV studios, restaurants, and small
retail spaces.
The SB48zP 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.
