Thirlmere driver choices

Folks, just getting back to where I can resume building......
Wondering if the choices for drivers in the Thirlmere line are still the CHP-70.2? Or other drivers?
Plan is to build with foam and glued cardboard first. Would like to have the option of the second (rear driver) facing up.
And possibly the mouth facing rearward.

I see Madisound still has these drivers.
