No I didn't (as I didn't know how to do this!).
Now, you said: The panel area on the 3 series is about 800 sq in (with the midrange part) compared to 609 for the 2.6R panel.
Leaving out the mid panel area on the IIIa - you get bass panel areas of:
* 620 sq in for the IIIa, and
* 609 sq in for the 2.6R.
So not so very different, I suggest. :-))
I never listened to 2.6Rs - I had had IIIas for about 15 years and when I reached the end of my upgrade path, I decided to try and create a IIIa which had a separate mid panel (to get rid of IMD - and vibrations from the bass panel getting to the ribbon cage).
After a couple of years looking, I was able to find the bass panels from a pair of 2.6Rs (which were shipped from Rome) ... and the mid/tweeter panels from a pair of T-IVas (which were shipped from Detroit).
The cross over uses stock IIIa slopes - although I tweaked the filter roll-off points slightly, to get a smoother overall FR. I use a 3-way active XO, using a miniDSP.
Yes, my subs are sealed (outside dimensions are about 3' high x 18" wide x 2' deep) with a 800w Hypex plate amp. So no servo-control.
Subs are in the front corners of the room - see here:
