That's the closest I can get to identifying these little units (exactly one reference).
5-1/4" stout little woofer (719 code suggests it was made Carbonneau) and small
dome tweeter. 16" x 10" x7" boxen. Haven't tried listening to them yet. They need
some attention.
I've been using various Acoustat ESL's (exclusively) since the mid 80's. There are currently two pair in use in my room. I was totally unaware of any dynamic speakers from them. The exception being the SPW-1 woofer which I own.
BTW: Thanks for the link. I've been relying on The Audio Circuit site for my information.
