Why no tweeter pic's? Hmmm...
Beg to differ... my Tempest LS-4 sport a "baby" Heil, as do other models in the LS series.Probably because they're "just" tweeters. The Tempest's don't use the Heil ribbon unit, not even a smaller one like some of the smaller ESS speakers.

4-ohms, minimum 25 wpc, max 450. Well a bit of latin jazz on these sound pretty good! Fast upper bass, good percussion. Even with dead tweeters....
Thanks, Michael. Do you by any chance have a spec sheet for the Larger Heil tweeter or any other Heil scans?ESS Model Nine and Tempest.
