Electro-Voice Sx80 Specifications page 2

Thanks to its molded-in attachment points and
available brackets, the Sx80 can be hung from a wall or
ceiling, stand mounted or used with OmniMount
Series 75 hardware.
The Sx80 can be used as a wide-range,
high-performance, easily portable music system with
the addition of the EV Sb121 12-inch bass module or
Sb121a powered bass module.

extended response. The horn/driver combination
also gives the Sx80 the ability to cover larger
areas than a small 16-lb (7.3-kg) speaker should
be capable of. Its projection and definition are
almost beyond belief. The coverage pattern also
permits the Sx80 to be oriented vertically or
horizontally with excellent performance either
way.
Ring-Mode Decoupling (RMD
® The Sx80 is equipped with EV's Ring-Mode
Decoupling (RMD TM ) originally developed for
X-Array TM concert speakers. RMD
domain resonances at their sources in the Sx80's
components and enclosure. These various ring
modes rob speakers of fidelity and unpleasantly
degrade the sound.
Thanks to RMD TM , the Sx80 sounds supremely
clean and accurate with pristine reproduction of
voices and instruments. It also maintains even
sound quality over a wide dynamic range thanks
to RMD TM .
High Power Handling
The Sx80 can handle 175-watts continuous,
700-watts short term for 8 hours according to
EIA RS-426A 1980 test procedures. Other small
speakers with high power ratings typically use a
light bulb to absorb power for protection when
their maximum output level is approached. The
light bulb acts like a compressor and causes the
sound quality to change relative to input power.
The Sx80 uses excellent component quality to
Sx80
(15.75 in.)/(11.49 in.)/(8.75 in.)
achieve its high power capability and turns
amplifier power into acoustic energy, not light.
To protect itself from the negative effects of
amplifier clipping or overload, the Sx80 is
equipped with EV's proven PRO
PRO TM circuit monitors the input level and only
activates when it is needed, preserving the
quality and dynamic integrity of the sound. The
high 92 dB (1W/1m) sensitivity and good power
TM )
handling insures that the Sx80 has serious output
capability.
TM attacks time-
Incredible Flexibility
The Sx80 has built-in flexibility to work in a
variety of professional audio applications. Its
nearly indestructible high-impact polystyrene
enclosure is rugged enough to survive the rigors
of transportation and the tortures of installation
outdoors in all kinds of weather. Molded into the
enclosure are inserts that allow the Sx80 to be
used with a variety of optional brackets and
mounts, including a wall/ceiling bracket, a
1 3/8-inch pole mount and OmniMount
Series 75. Sx80s are available in black or white
(Sx80W) and are easily paintable to meet decor-
conscious applications.
For wider bandwidth, higher impact systems, the
Sx80 can be combined with the EV Sb121 or the
Sb121a (amplified) bass modules for a high
output sound system that is light, compact and
unobtrusive. Inch for inch, pound for pound, the
Sx80 can't be beat.
