The Soavo-900SW Subwoofer meets the challenge of providing an ideal balance between tight
sounds (with crisp, fast attack) and deep sounds (with a spacious feeling). Designed for extremely
accurate music reproduction, the Soavo-900SW proudly takes its place in Yamaha’s Soavo series.

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.
