Tweeter Help please

Morning guys,

Can anyone recommend a warm ish sounding tweeter thats mounting is 40mm to go with my Audison 165 mid drivers?

I really liked the Dynaudio MD102 but these are about 50mm and wont fit in the OE dash location, which is tight up against the windscreen so there is no way that i can get a tool in there to enlarge them.

Cheers!
