Anyone Familar With ESS Speakers?

I owned the AMT 1A's in the mid-70s and thought they were the best thing I'd ever heard. But this was my first "high end" system after graduating from college and these speakers replaced some little AR bookshelf box speakers. The woofers rotted out after a few years, and the cloth lid contraption didn't hang right after a while. I guess the tweeters were a *little* bright, too. I gave the speakers to my sister in 1980 and she still uses them! The woofers are probably not even functioning by now, but she doesn't notice it. anyway, if someone is giving you these speakers, sure, try them out, but for even a couple hundred dollars you can buy much better used speakers these days.
