It could be since I never measured from the inside of the door frame area to the speaker screen, but I doubt it. I can visually inspect the speakers and there is a gap between the current tweeter (I have the sps-400's now) and the grill.
Alpine says the tweeter is adjustable. Maybe a few degree on a single axis parallel to the main driver is what I would venture is an educated guess.
