Further Information:
Ultra rare in Australia, from Canon Audio's 1990's foray into the world of loudspeakers and acoustics.
I have a pair of S-30s and matching S-U20 passive subwoofer.
All work perfectly and sound as they did some 30 years ago. Fantastic history to the design and development of these wide imaging gems.
Cosmetic marks, especially on the subwoofer.
These were never distributed here in Oz, so probably the only trio on offer. Ever...
