If you really aren't going to use them - I'm actively looking for drivers to use for a 3-way setup - I was thinking of dome mids in the very corner of my windshield and an ambitious aimed ribbon tweeter A-pillar panel...
But now that I look up what you have, those might work in my dash corners with some simple sail tweeters essentially functioning just as super-tweeters.
Don't suppose you want to partial-swap for some 3"x3" BG planar mid/tweets?
I don't know what you have into those, I believe you got them used but I know those were never cheap... I might be interested if you want to shoot me a message.
I'm so early, not ready to install for even testing, so it might be a bit of a reckless purchase, but I'm intrigued.
I'd love to hear more about your aiming experiences. Shoot me a message!
