Couldn't pass up these Foster compression horn tweets from Parts Express. They're regularly $99 but on close out for $15. Foster is the parent company of Fostex so the quality is good. At 100dbs they need to be tamed by a cap and I'm trying a .47uf at the moment to be paired with 93 db Fostex Tektons. I had some old grills ( wave guides ) from Sansui horns that fits nicely.
