I have always found horn and bullet tweeters to be quite harsh, therefore I always thought them to be entry level quality. It also seems that bigger tweeters are gentler on the ears. I currently use a/d/s 336is.2 tweeters that are 1-3/4" diameter. They are mounted high on the A pillars reflecting off the windshield. Does it make sense? Not to most people, but to me, it sounds just right.
Reflected or reverberated sound can be aimed; that’s why tweeter horns are a thing. Angles matter more and more the higher Hz you’re dealing with.
