I have a pair of ES-12's. They do use Vifa speaker components. 12" woofer, 6.5" mid bass and a 3/4" dome tweeter. Kind of look like small Magnepans. I bought these in the late 80's. I think the company went out of business sometime around 1990/1991. I too could not find anymore info about them. Agree with Bryceeboy, good looking units and still sound great in the second system.
