EAW SM155 Specifications

• Flat frequency response for maximum gain
before feedback
• High acoustic output capabilities for large stage
applications
• Wide bandwidth enables full production
capability through monitors - including kick
drum and bass guitar
The SM-155's wide bandwidth (48 to
exceptionally smooth frequency response (
midband) and high output capabilities make it an ideal
choice for stage monitoring in clubs, auditoriums and
concert halls. Its true, uncolored audio reproduction gives
you an accurate picture of what you are doing on stage. The
cross-grainlaminated birch
enclosure offers ruggedness, portability and flexability far
superior to competitive systems made of lesser materials.
The SM-155 is built to the same standards of advanced
acoustic design and master craftsmanship that make EAW
the first choice for high output systems in demanding
professional applications throughout the world.
The components inside the SM-155 include two high
technology RCF drivers and a specially
equalized, third order dividing network. This combination of
advanced RCF drivers and sophisticated EAW electronic
interface results in a system with the smoothest mid-band
response of any high output monitor made today. In
addition, unlike other monitor systems, the SM-155 uses a
large inch diameter diaphragm, compression, high
2
frequency driver which works right down to
smooth response. This permits the elimination of narrow
band response spikes and results in considerably more
usable broadband gain before feedback. (As much as 10 dB
more gain as compared to simple 1211/tweeter designs.)
The SM-155's low frequency section includes a RCF383,
extended bass, inch driver combined with an optimally
12
vented enclosure. This results in bass response previously
unattainable in a compact
reproduction of the full stage production, including kick
drum, through the monitor system.
