Yes I too, Have a pair of ESS AMT (Model 5) and just this last week pulled them out of the garage to find that all surrounds on the 10" woofers and 10" passive radiators were non-existent....so I bought two new OME 10" woofers with 125 RMS handling and bought two new OME passive radiators and of course I had to rubber cement them to the existing octagon shaped aluminum frame and them remount them in the back of the cabinets... ESS put alot of science into their sound from what I can hear...loud, quiet...either way they are crystal clear and very responsive no matter how much power they are running on...20, 30 or even 90 watts...these have got to have the biggest boom for the smallest power consumption over all and usually that is the goal when a passive radiator is present in the cabinet(setup)......Now some trivia questions that I would like answers to: What year did the ESS Performance Series (Model 5) come out? How much money did a pair of these speakers cost when they first hit the shelves? Was ESS top-of-the-line for its time? Why did ESS shut down (go out of business)-(in Southern California?) Thank for for you interest in ESS VINTAGE AUDIO as much as I am -- Dave
ESS speakers synergise with valves?
I recently bought a pair of old ESS PS5C speakers.These use a small Heil Ribbon,a ten inch mid woofer and a rear mounted ten inch passive radiator.
I started out using some of my SS amps amps with these and whilst I could hear that they were doing some things really well,felt that a hollow and slightly coarse midrange detracted from their overall sound.They had a typical 'west coast" sound,although infinitely better sounding than their JBL contemporaries.
To combat this I doped the woofer with liquid silicone.This is often a subtle but very effective way of reducing paper cone colourations.
The next day I changed amps to 23 watt EL34 Trimax monoblocks,never really expecting them to drive them properly.But was I ever wrong!
The sound from this combination is simply amazing.These are now incredibly neutral sounding speakers,with fantastic bass,clarity and imaging.
Anybody who has been using valve amps for a while comes to know that they very rarely achieve their potential with mainstream speakers.So when we discover one that is the exception to the rule we need to announce it.These ESS may not to be to everyones liking-they are quite analytical,but on balance I think they are still a real find for tube lovers.With a 300b SET amp they could really be something.
Just to confirm the ease of driving I have also run them with a Tripath 10 watt class T amp.Not as good as the valves but still drives them quite loud before clipping and sounds better than SS.
Has anyone else discovered these?
