Selenium ST324 Super Tweeter ABS Housing

Mounted these on top of a big 2-way EV 15" with horn and they sound great with lots of sparkle everywhere in the room.
Crossed over 18 db /oct @ 5K.
Very efficient and not too expensive. They're the real deal and far superior to all the cheapo piezos you can pile on.

its the best ever

Have a 2 way pro-sound speaker ?
These tweeters are a great way to "open up"
the highs and deliver a more spacious and "live" sound. Be sure to follow the mfg's recommendation
and cross over at 5khz or above. Roll off your present HF driver at the same frequency.
