I've never heard of Clements, but to be honest, there have been a million different speaker companies. Still, I barely find any indication that they ever even existed. I'm guessing this is an uphill battle to find detailed info. But good luck, and keep looking.
Do you have them, or why are you looking for info?
I have them and want the specs. They were made by Phil Clements who also designed speakers for Solus Audio and Phase Research. There is some info on AudioKarma and Steve Hoffman forums but not for the specific speakers I am asking about.
