Yamaha Soava Natural Sound Speaker System - Manual (Page 15)

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.

Independent Direct Crossover Connections
Yamaha’s total commitment to achieving rich and
vivid sound is seen in the design of the Soavo
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.

restrict standing waves, preventing
degradation of midrange sound.
