No. Well, ok it could be done. But, you'd have to scavenge the annular plugs and poles from another set of drivers, do some machining, then have the drivers re-magged once assembled and poles centered. It would be a lot of work for questionable gains.

34647 would be the 8 ohm phragm.

Since this was the "theater" version it would stand to reason that they also made 802-16T's, sorry i don't have the 16 ohm phragm numbers memorized.

I suspect OG is right and the early versions were in the old style body with annular slit phasing. They even went on to make a "T" version of the 902, at least long enough for it to make a catalog appearance.
