Find some used Image Dynamics HLCD horns.

Haunz, years ago I took a pair of 2" compression drivers and removed the back chamber (which actually reveals the front of the titanium diaphragm), as well as the compression chamber/phase plug area on the rear side of the diaphragm (which provides the proper compression/throat area before the actual horn), then placed the metal cup/chamber on the true back side of the diaphragm with some heavy felt to absorb the rear wave. It would be on the large side and a bit directional regarding off-axis response but it will also be some of the most effortless and dynamic playback you've ever heard. You can address the off-axis response with a foam ring in front of the diaphragm to resemble the power response of a smaller dome. I used them on a very clean 75 watts crossed at approximately 500Hz my pain threshold was reached far before the driver's limits were. You can find pretty good deals on PE for some 1", 1.4", and 2" compression drivers. High efficiency, low power compression, low distortion.

Do it.

^^^How was the upper end response on those?

Once the foam ring was in place and a tiny bit of EQ love was applied to relax the midrange, it was superb. This pair had a copper sleeve on the pole so inductance was super low.

Upper end response on compression drivers usually suffers as the result of a poor phase plug/compression/throat area. Once that's out of the mix, they perform very smoothly with great extension in both directions. Newer compression drivers have much better phase plugs but that would only apply if you were going to use it with a horn, not what I'm describing here.

LOL, I like the way you think...

There are a bunch of compression drivers laying around my dad's sound shop.. I might have to grab a couple and try what you suggest...

Thx for the input !

I know Audiopipe makes a 6" bullet tweeter.

I heard the 3's, they were possibly one of the worst things I've ever heard.

It's Audiopipe, what do you expect?

the 6"s might be two times better.

the 6"s might be two times better.

lmao. probably not. bullet tweeters are awful. compression drivers can be awesome.
