They are nice drivers. Especially in small sealed enclosures. I have put them in doors because I already have them from my previous build and I wanted to try, but they worked well in doors too.
But I'm annoyed by the rattles I got despite the fair amount of sound deadening I have added. The midbass is the weak point now.
Wow! Fantastic work - very impressive fabrication - they look like they belong from the factory. How are they secured to the door card? Im looking forward to hearing your impression of the sound once everything is done.
