Cast Composite Enclosure
SoundTube’s RSi Series cast composite
enclosure provides a low-resonance plat-
form with effective self-damping properties
for a clean, tight sound. Compression
cast glass-fiber composite material coupled
with SoundTube’s patented ZeroReflec-
tion™ internal shaping provide extreme
stiffness, eliminating internal standing
waves and external diffraction distortions.
The result is accurate sound and tight bass
in a commercial speaker.
