Well, it's a special tweeter that isn't generally sold seperately to the public. Trust me, the off-axis is more than great...
I can't say what they are because I don't think it would be a good idea to (or very sporting at the least) without explicit permission. I'd probably be able to say after the install, though.
What are Sail Panels? There is no place to mount the tweeters higher up on the door if you look...when you close them, the tiny A-frame gets smushed up against the dash.
