There are 2 pairs currently for sale on Australian ebay. Both pairs are located too far away to consider an inspection before bidding.
Similar pricing to recently advertised 4320s
Both listings indicate speakers belonged to the ABC, and may have been used as studio monitors.
My main question is the woofers appear to have very different surrounds. One even appears to not be circular (optical illusion).? From information on this forum original surrounds were possibly a lensaloy? material, so these are probably not original.
Any thoughts?
