Music as it should be heard.
the original sound of musical
instruments, and of the human
voice, so they should be
reproduced with nothing added or
taken away. Giving you this
beautiful music experience is the
reason we created the Soavo
series. Listen to Soavo and
discover how truly natural music
from a speaker can be.
At Yamaha, we love, understand
and respect music. We’re sure
that you love music, too, and that
when you listen to it, you want it
to sound as natural as possible.

Yamaha’s involvement and passion for music
goes back more than a century to when we built
our first reed organ in 1887. Now we are the
world’s leading producer of pianos and other
musical instruments and are involved with music
in many other ways as well. We manufacture
professional recording equipment, we design
concert halls and we assist artists at concerts
with regards to set up and sound tuning.
This knowledge and experience benefits our
production of speakers in many ways. In fact,
the very first speaker we made was used in a
musical instrument — the Electone® electronic
organ. For the Soavo series, our speaker
engineers took advantage of Yamaha
expertise in many areas, including
woodworking, metallurgy, acoustics, sound
processing and even piano tuning.
But the most important factor is our
commitment to maintaining an extremely
high standard of sound quality that we call
“Natural Sound.” You can hear it in all of
our musical instruments, and now we are
proud to present one of the finest examples
of Natural Sound performance we have ever
created: the Soavo speaker series.

Soavo Design
Higher performance
through innovative
design.
In order to achieve the most natural music
reproduction, the Soavo design team spent five
years of research, planning and development. They
created a unique cabinet design, which is shaped
and reinforced for optimum music reproduction.
They also used the expertise of Yamaha wood
craftsmen who produce our grand pianos, selected
acoustically excellent wood, and gave it a high
quality piano-type finish. Every material and
design aspect was carefully considered, even down
to the feet. The result is beautiful speakers that
bring forth out the full potential of the music.

DRIVERS
Advanced PMD Woofer and Midrange Cones
In order to provide very fast attack time
(sound rise and fall), as well as excellent
midrange clarity and bass response, Yamaha
developed Advanced PMD (Advanced Polymer-
injected Mica Diaphragm) cones that are
extremely light, rigid and sturdy. They employ
characteristics decrease unwanted
resonances to achieve the smooth frequency
response that results in natural sounding
vocals. The midrange driver creates a feeling
of presence as if someone is actually singing
in the room, while the dual woofer design
delivers deep and tight bass.
a low specific gravity material called PMP
(Poly-Methyl-Pentene) that is much lighter
than either paper or polypropylene. Precisely
determined amounts of mica and talc are
added, which testing has proved contribute to
the beautiful quality of sounds in the vocal

Aluminium Dome,
DC-Diaphragm™ Tweeter
The high-performance 1” (3cm) aluminium
dome tweeter delivers crisp and clear highs
at all power levels. It employs a fully
integrated diaphragm/voice coil structure
called the DC-Diaphragm that eliminates
extraneous materials for a cleaner sound. It is
extremely light yet durable, and for a small
unit transmits an extremely large amount of
detailed sound information, resulting in a
denser sound field.
Germany. Diecast aluminium baskets ensure solid
support for high stiffness, improving sound image
localization and depth reproduction. The
midrange driver is powered by a newly designed,
compact and powerful neodymium magnet.
Carved Wooden Port
Each port is carved from carefully chosen, high
quality wood. The port has very thick and rigid
walls and a flared shape, ensuring a smooth
sound flow that contributes to bass sound with a
more spacious and massive feel.
Tweeter Plate
A diecast aluminium tweeter plate isolates the
tweeter from cabinet vibration and provides a solid
attachment for the tweeter unit, so the high range
sound is clear and transparent, with no colouration.

Possible Performance

Innovative Cabinet Design
One of the keys to Soavo’s ability to
deliver Natural Sound music reproduction
is the cabinet design. While maximizing
sound clarity and imaging, the designers
strived to drastically reduce internal
standing waves and produce an expansive
sound with an exceptional feeling of
depth. Their solution was to create a
cabinet with non-parallel sides, divide the
woofer and midrange sections by a slanted
partition, and strengthen the interior with
large, vertical ladder-type bracing.
Three-Way Mitered-Joint Construction
for a Rigid Body
Yamaha’s excellence in woodworking is used
to good advantage in the three-way mitered
construction of the cabinet joints. This
technique ensures extremely tight joints so
the entire cabinet behaves as a single unit,
providing tight bass reproduction.
Diecast Aluminium Stands
The Soavo-1 is equipped with diecast
aluminium stands that provide the
necessary solid floor contact for tighter
bass and increased stability.
Yamaha developed the Soavo speakers to provide extraordinarily realistic music reproduction.
We accomplished this through a combination of advanced speaker engineering, use of the absolute
best parts and materials available, and an innovative cabinet design.

Yamaha’s total commitment to achieving rich and

networks. They use the highest quality parts, including
Solen metalized polypropylene capacitors of France
and large hollow centre coils with carefully selected
wire. Furthermore, rather than using printed circuit
boards, each connection is individually soldered on a
thick wooden board, providing larger, shorter signal
paths for maximum sound quality. Woofer crossover

Heavy-Duty Construction with Three-
Way Mitered-Joint Construction
Yamaha uses three-way mitered-joint
construction at the cabinet corners and
baffle/body connections to increase joint
tightness for better response and less
vibration. A thick (1-1/2”; 37mm) baffle
also reduces vibration.
High Performance Driver
The 10” (25cm) F.B.P. diaphragm driver uses
a new Yamaha-developed material
consisting of paper with a blend of carbon
and aramid fibers. Its extreme stiffness and
extra-long stroke prevent distortion from
occurring even during large, deep bursts of
sound. A large, powerful magnetic circuit
also contributes to the driver’s fast
response. The unit is firmly supported by a
strong diecast aluminium frame.
600W Digital Amplifier
The Soavo-900SW has a high-end audio
component built in! — a 600W digital
amplifier. Featuring the same power chipset
as the high-end MX-D1 digital amplifier, it
delivers exceptionally high levels of power
and sound quality, yet with low power
consumption.
