What sets the SxA™family above all other powered
loudspeakers is the name on the box: Electro-Voice®
Professionals know, use, and trust their sound to
EV®. We’ve been building loudspeakers for
75 years, and amplifiers for more
than 50 years. Only Electro-Voice
can put all that innovation and
experience together to build
powered speakers that
work so well in so many
different applications.
Electro-Voice has a long track record of important loudspeaker innovations.
While other speaker manufacturers ramble on and on about their products,
just remember that a lot of the technology they use was invented by Electro-Voice.
For example: Other speaker manufacturers often talk about their “constant-directivity”
or “CD” horns. Electro-Voice invented and patented CD horns and ours do the job right,
accurately spreading the full range of music and speech across their coverage pattern.
Electro-Voice “firsts” such as flat-wire voice coils, pure titanium compression driver
diaphragms, and equalized crossover networks set the technology pace for the industry.
Innovative thinking...
...in every product
Electro-Voice also sparked a revolution in loudspeaker
design more than 25 years ago when we created the pro
audio industry’s first lightweight, high-output speakers.
Today, more than a million EV®lightweight speakers are
used around the world, many in places you wouldn’t
expect such as Notre Dame Stadium, Broadway theaters,
and large churches. Nobody has more experience with
professional lightweight speakers than Electro-Voice.
SxA™powered loudspeakers are the newest members
of our highly successful line of Sx Series™lightweight
speakers. Like the Sx Series, SxA powered loudspeakers
demonstrate that we don’t just reserve our best
innovations for our most expensive concert systems.
When the name Electro-Voice is on the box, you know
you’re getting the best in the business.
Electro-Voice Constant-directivity horns maintain their
coverage patterns throughout their frequency range.
Other CD horns often collapse coverage in the
vertical plane at high frequencies.

SxA technical specifications
Why they sound so darn good: SxA technical notes
SxA two-way powered loudspeakers borrow a key technology from
Electro-Voice®concert systems: our exclusive Ring-Mode Decoupling (RMD®)
technology. RMD identifies and dampens acoustic and mechanical resonances
that would color the sound. The result is pure vocal reproduction and the
smoothest, most detailed mids available. Thanks to RMD, the sound quality
doesn’t change at different listening levels.
High-current amplifiers with beefy power supplies are perfectly matched to
each SxA driver. “Over-easy” limiters built into each SxA speaker prevent amp
clipping from damaging the drivers, and preserve the spectral balance of your
sound — even when pushed hard. The amps contain 24-dB-per-
octave Linkwitz-Riley crossovers and customized signal
processing to make the speakers sound their best.
SxA100 and SxA250 reproduce high frequencies with
the Electro-Voice®DH2010a, one of the best sounding
and most reliable drivers available. This pure titanium driver
is coupled to our TimePath™phase plug for smooth, extended HF response.
Both SxA100 and SxA250 have narrower-than-typical coverage to control room
surface reflections and to throw their sound farther, improving intelligibility at
the back of the room.
With their intelligent design and well-integrated components and amplifiers,
the SxA family of powered loudspeakers deliver beautifully balanced sound in
real-world applications.

The power to reach your audience.
Musicians, MBAs, ministers — anyone who stands before an
audience depends on a sound system to excite, to motivate, to
inspire. That’s why we developed a family of powered loudspeakers
that anyone can use: Electro-Voice
®
SxA100 and SxA250 full-range
powered speakers, and the SxA180 powered subwoofer.
Everything you need for high-quality sound reinforcement is packed
into these self-contained, easy-to-transport-and-set-up systems.
There’s no separate amplifier rack, no complicated wiring. The SxA100
and 250 full-range speakers include built-in two-channel mixers with
mic and line inputs and two-band EQ. Just connect the SxA™speakers
(if you’re using more than one), plug in the power, plug in a microphone
and maybe a CD player or keyboard, and you’re good to go. Whether
you’re a band on tour, or a salesperson making a presentation, SxA power
loudspeakers make it easy to sound your best.
The power to reach your audience.
SxA for musicians
No matter what kind of music you play, there’s
an SxA system that’s perfect for what you do.
The range, clarity, and projection of SxA
powered loudspeakers ensure that the audience
hears every note, every nuance of your
performance. SxA100 is superb for solo gigs in
small-to-medium rooms when you just need
reinforcement for your voice, acoustic guitar, or
keyboard. For more volume, and warmer, richer
lows, you’ll want the SxA250. You can always
turn an SxA on its side for a self-powered floor
monitor. And when you play bigger gigs, add the
SxA180 powered subwoofer for chest-pounding
bass that fills the space with full-impact sound.
With so many uses, you’ll never outgrow your
SxA powered loudspeakers.
SxA for DJs
SxA powered loudspeakers provide
the energy and excitement that
dance grooves need, with plenty of
power and clarity to cut through
crowd noise. Add the SxA180
powered subwoofer to your system
for the classic Electro-Voice
thundering bass that gets the whole
room shakin’. For DJs, the SxA250 is
the way to go for rounder, fatter
sound and higher output. All SxA
systems are easy to setup, tear
down, and load out. Convenient pole
mounting of the two-ways above the
SxA180 sub eliminates the need for
separate speaker stands. The SxA
family is amazingly compact for a
system that sounds so big.
