ESS Heil is the legendary American brand for designing and producing high quality loudspeaker drivers with 40+ years of history.  As the original patent holder of Air Motion Transformer, ESS Heil is part of the audio history, and the driver is considered 'sound as clear as light'. 

The legendary Heil AMT highs are natural and full body to an extent that is rare to find among tweeter drivers. This is also a dipole driver that adds to it’s match to open baffle product offering.

Past customer feedback:

“… the speakers breaking in nicely. Have them temporarily set up on an cheap amp streaming. Even that setup is pretty cool. I could hear the changes happening so dramatically in some cases. Last night i played a song I played the day before and I was like “is that the same song :-)”, “… The AMT Heil are very clear and enormous details… and of course a massive punch from the 15″ woofers. Played Kodo and the walls were shaking.”, Markus, Customer USA
