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-  
tioninternal shaping provide extreme  
stiffness, eliminating internal standing  
waves and external diffraction distortions.  
The result is accurate sound and tight bass  
in a commercial speaker.
