Heil AMT's - anybody have any experience ?

I had a pair of ESS Heil AMT 1b's new from about 1978. They sounded great especially for Rock music. I drove them at the time with a HK PM660 integrated. From a audiophile standpoint there was a bit of a rough spot in the crossover from the mids at the bottom end of the air motion transformer unit to the bass cone driver but, back then, who cared?! The Heil tweeter was so fast that nothing really mates with it seamlessly. These Speakers made it through my college days. They were bullet proof.
Happy Listening!

I think you will find the more modern implementations of the Heil driver by firms such as Oskar, Mark and Daniel, Adam, etc, are superior to what ESS did back in the 70's. I'm a fan of Oskar loudspeakers.

I had ESS speakers back in the early 80s, great speaker with thunderuss bass and crisp midrange, nic etechnology and also curious to learn what happened to them.

Heils...excellent for their time, but not out classed by new speaker tech. My father has the top of the line Heil (Heil Tweeter, 6" midrange and 2 x 10" woofers). We did an A/B listening session against the PBN Montana SPX (traditional dynamic speaker) and the Heils were out classed in every way.

The new Heil offerrings are the way to go. Midranges have improved greatly and can keep up with the Heil.

The old Heils were great for tube amps and vinyl records. Using the tweeter nowadays in a DIY approach is great for the hobbyist. The new woofers by ESS are lethargic at best. Use a Peerless or Vifa woofer combo to get better results.
