Could be something like that. I had family and relatives who worked in the original EPI factory in Newburyport, I used to go in from time to time to visit and get a small tour. It was a very laid back environment there. They had a pair of 1000 towers hooked up there, they were great in the days at $1000 each price tag, that was a lot of money in the early 70's. When production ended in Newburyport the guy who owns Human speakers worked for EPI, he bought a lot of the original tooling and machines from the factory floor to make original EPI woofers and tweeters.Maybe it was EPI badged speakers had black cones and Epicure badged speakers had blue cones?

In my industry, EPI is Electro Plasma Incorporated (they were in California), which was consumed by the company I formerly worked for (Sulzer Metco; currently Oerlikon Metco). They (EPI) made vacuum plasma systems and in those chambers made tungsten rocket nozzles, among tons of other things.
Vacuum chamber production was moved to Switzerland, where I worked with one for a while. I believe the only documented use of cold spray in a vacuum chamber, ever (on this planet anyway).
No, you don't get those 30 seconds of wasted life reading all that, back.
HUH???
20s for when those ebay links die. This is a set I refoamed.

I much prefer the looks of the 20+ with the front lower half in veneer.
Interesting to see the drivers recessed in the 20 but the tweeters appear to be surface mounted in the 20+ shown at the top of the page.
Energy. They are supposed to sound great but most are missing a tweeter or two, so I have never heard them.I used the tweeters to replace the "million dollar" tweeters in a pair of speakers made in Canada, but I don't remember the brand...but the model was "pro22."
