The term "rare" gets tossed around on eBay a lot and in many ways has lost some of its impact, but in this case the term really is appropriate because they rarely come to market. Even photos can be hard to come by online. These Isophon speakers stand out for two important reasons:
1. They have been fully recapped and serviced and sound warm and clean due to their rather low impedance of 3 ohms.
2. These come with the center channel speaker which never happens.
These were lovingly used as part of my own setup which included a legendary, fully restored Scott LK-72 tube amp which I also have listed in a separate auction here.
Feel freer to ask any questions and happy eBaying!
