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,engineeredbyEAW,providethehighestoutputandbest
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
constructionarerequired.
TheSB150zP isa high output, compactsubwoofer system.This
versatile, all-purpose subwoofer is designed for permanent
installationwherethesolid-sounding output ofa 15 inch driveris
desired. The SB150zP works well with most full-range
loudspeakersinavariety ofapplicationsincluding:smallhouses
of worship, A/V systems, hotel ballrooms, meeting rooms,
classrooms, exhibit areas, f/x reinforcement, cruise ships,
cinemas,TVstudios,restaurants,andsmallretailspaces.
The SB150zP is designed to be used with today's sophisticated
digitalsignalprocessingtooptimizetheLFresponse.EAW'sMX
Series processors are recommended for the required crossover
andequalization.
