Anyone remember Studio Design speakers?

There really is very little on the web

I thought some models bore a passing resemblance to some Ohm speakers and considering the “connection” between ownership of Ohm and Tech Hifi, a resemblance is not surprising. 
I had the 46’s. 10 inch woofer, porter box and what was a very common tweeter- phenolic ring cone tweeter. 
Crossover was bare bones- a single capacitor as I recall. Efficiency was pretty good too 

I worked at Tech HiFi and i never seen those speakers their, we sold infinity, JBL, Ohm, Nakamichi, and other Brands in are New Haven Conn Store, but i did see them sold out of Vans. i think they had white woofer cones then clear cones.at one time i think they got busted on 20/20 show and another van speaker was Acoustic Response,

Actually, if you search out old ads - say 1977 or so, for tech hifi, you will see Studio Design advertised.
