This
configuration has proven itself the cost effective answer to
high output monitoring applications with many sound
companies around the world. EAW has refined this classic
with a number of improvements optimizing the system for
maximally flat response and wider bandwidth. The two inch
entry horn lens offers better dispersion than the small
exponential horns typically used in small enclosures. The
smoother response and wider dispersion of this desiqn
allows for improved coverage and more gain before
feedback. When stage positioning calls for tight coverage due
to spill problems, the lens can be easily removed for a very
tight 451 conical dispersion. The interchangeable tuning
assembly allows for optimum box/driver alignment with all
commercially available high efficiency 15 inch drivers. This
feature, unique to EAW, lets you make use of existing
drivers and still maintain optimum low frequency
performance It also allows for future driver updating with
ease while maintaining box alignment.
Options for the SM- 152i-CT include a tweeter horn driver
cutout and crossover, one inch entry horn lens, and passive
800 Hz crossover for full passive operation.
Physically the SM-152i-CT will sit at three angles for
maximum versatility. Most angles provide excellent stage
sight lines and this remarkable package requires very little
floor space making it ideal for use in crowded stage
applications.
SM-600-CT The SM-600-CT is designed to offer the highest
output capabilities of any stage monitor system available. The
low frequency section consists of two 12 inch drivers
providing a sensitivity in the range of 100 to 104 dB SPL with
one watt at one meter. The actual efficiency will depend on
the drivers selected. At the recommended crossover
frequency of 800 Hz the two inch entry exponential horn
takes over with its nominal 90* by 40* coverage angle. This
translates into a maximum output capability of 128 dB SPL at
I m with two EAW/RCF LF-300-R bass drivers and a JBL
2441 high frequency driver. The unique interchangeable
tuning system allows the SM-600-CT to work well with all
high output 12 inch drivers. Optional features include
tweeter crossover/cutout and passive crossover.
