2010 C70 speaker replacement

[patnshan]

The title says it all, I am in need of replacing my 2010 C70 speakers. It is the non-dynaudio system. The front driver door speaker is clearly blown although the incompetent service guys say "I can't hear it".
Regardless, I am wanting to get some aftermarket speakers to replace the door speakers and can't find definitive information on what the speaker sizes are. It seems there is a large driver in the lower door with a separate tweeter in the upper door. I am thinking 6.5 inch separates but need it to be cosmetically neutral so depth might be an issue as well.
Has anyone done this or does anyone know the sizes of these speakers? I want to pull the door panels off only once and hope I can confirm this here.
Thanks much for any help!
