When we discovered the speakers in our ESS1a units had lost their foam rubber surrounds, we also found one of the passive radiators had gone bad for the same reason. The SimplySpeakers repair kit was easy to use. The only requirement is to clean the original mounting frame thoroughly and preserve the gasket. I replaced one passive radiator and am monitoring the other original one because it is still good. Our ESS1a speakers are now performing like they did when we first heard them in a showroom years ago.

ESS Passive Radiator
This is just a note of thanks. I ordered a new set of passive radiators for my ESS Heil AMT1-A speakers on Nov 6. They were shipped on Nov 7 and I received them on Nov 9.
Great service and speedy in delivery. You beat Amazon which usually takes longer. I talked to your tech guy first and he was a big help in helping to decide what to get.
I installed the new radiators and they are just fine – my bass is back to where it should be on these great speakers (originally purchase in 1976).
Thanks again for your great service and keep up the great work!
