I can't be sure but I think mine were done with conventional front roll surrounds ,they had done SFB3s at Wembley before when I asked.It was a few years ago ,the only issue I found was that two of the bolts on one of the drivers weren't quite long enough.

These speakers, or at least the woofer and mid, probably get all their cone control from the spider, and the surround is just there to hold it together.
Thanks Tony, that should really help nail down suitable candidates.
OK I get the idea. We deffo need a flat attach for that one.Thanks Frank, I’ll also give you a ‘D’ measurement for the 12” as if you have a look back over the last page you’ll note there is a very defined edge contour to the cone, it bends through a right angle, i.e. a long flat overlap is not possible. My best guess is 237mm, say a 4mm surround attachment area on the rear. There is no such issue with the 10”.
Am watching this with much interest.
