Spendor SP 1/5 Monitors

Where do you get the idea that Spendor makes or ever made a model called 1/5? I don't recall this, and looking at the history page at www.spendoraudio.com, I don't see it. There was a British company, one of the firms that made a version of the LS3/5a, that I think made a larger version inspired by the LS3/5a and the name had "/5" in it, perhaps 1/5. But I think it was Rogers, not Spendor. I may be wrong, I'm relying on memory.

Well, other than that what real evidence do you have ; - )

Biwiring is relatively recent offering in Spendor's world. That's one clue.
