refoaming smaller Advents

I'm about to refoam a pair of smaller Advent speakers, but I can't tell if the surrounds are supposed to be convex, or concave. Which way are they supposed to be installed?
 
On the 9" woofers (Small Advent), the surround is convex (roll facing OUT). The same goes for the Advent 2, only it uses an 8.5" woofer.

On the 10" Large Advent woofers with the masonite ring, the surround is concave (facing IN). However, on the later model Large Advent woofers with the bevelled metal frame edge, the surround is convex (again, facing OUT).

Regards,
Gordon.
