Ess Company

I owned the Rock Monitors way back when.  
They were cool speakers.  

ESS Sacramento, when I worked there, had a once a year employee sale. Everything for sale was placed in the parking lot. Salary employees got the first pick. Us hourly employees had to wait till we were off of work. I scored a pair of 4-12T  (tower) speakers for 30 dollars each. Happy days, only to have them stolen 6 months later. R and R. (Research and development) had speakers from other companies.... to see what made them tick. Had so many there I asked them if they had any they wanted to sell. Happy days again. They did not give them away (almost) but I paid much much less than in retail stores. I bought a few speakers that were in dusty box’s. I met Mr. Oscar Heil there. ESS also had a live band there once set up in the warehouse. They also paid for get together’s (food and drink..... mainly drink) at a local park every now and then. Those were the days.

@jimess  Thank you for starting this thread.

My dad got a pair of AMT1 when I was a child, and I have them in my house here.  We used to rock out pretty good with them.  Really nice speakers at that time, but even better memories

The ESS speaker I would still like to find is the Super Quad. It used the original Quad ESL for the midrange, with the same transmissionline-loaded Kef B-139 woofer and RTR tweeters as did the Transtatic. Not many were made---it retailed for $2000 in the early 70's, same as the Infinity Servo-Static, to which it was intended to provide competition.

Had the ESS Rock Monitors as well in my  rock days with Kenwood 700 amp sounded great.
