ESS speakers "Translinear" Transstatic

By the way, it's been a long time, but I have never hated those ESS speakers the way so many have. The 12" woofers did need to be replaced, due to the surrounds rotting out. It's in the back of my mind to go through them, and see what happens. Does anyone know the crossover point of the speaker? How low the Heil AMT can be crossed over? Any other bits of wisdom? Thank you, Joe

In response to Trelja's question - the crossover of the orignal ESS AMT speakers was set at 1,000 HZ. The most recent version use 800 HZ. The Swiss made Oscar Kithara has a crossover at 730 HZ. While the ESS speakers had midrange problems, I'm not sure why anyone would hate these speakers. The clarity and openess of the Heil puts a lot of high dollar speakers to sham and works wonderfully for a lot of rock and electronic music. The midrange deficiencies of the ESS designs caused by blending a large slow woofer with the ultra fast Heil just made the ESS a poor choice for jass and vocal enthusiasts. I understand that some the recent designs that use the Heil do not have this midrange problem. Alas they are not easily avaialbe in the U.S. The Swiss company Precide distributes the speakers.

I bought the AMT-3 Rock Monitors in 1975, and still have them in my basement being driven by a Pioneer receiver. I've twice replaced the two 10" woofers and Heil diaphrams. The mid-range is still the original. With a sub-woofer, it still sounds very good. It was my main speakers until about 5 years ago. I now have Legacy Focus speakers in my SACD based main system.

Thank you for your information Rurdangaray. I am most appreciative, Joe

Hi,

I have owned the ESS AMT-3's since 1975 and have the foam rotting problem. I prefer to purchase equivalent drivers (10's and 6's) rather than refoam. Greatly appreciate driver specification data and/or any info on replacement driver manufacturer and p/n. Thanks.
