Hey Planet10, could you keep an eye out for some particular drivers for which I am on the lookout.
I would like to find some mates for those organ speakers I salvaged (at least the 10" and probably the 15 and 6x9 too).
The numbers are
15"
661056, 27273, 2207421
10" driver:
668459, 24651, 2857420
Oval driver:
651805, 21739, 2857407
They are from a mid 70s vintage Wurlitzer console organ. The 15" is 8ohm and the 10" is 16ohm. I havent measured the oval yet. That 10 is a nice high Q driver with whizzer that I would like to try OB. The fs is a little high (87) but might still be useful.
Some pictures.

I was using my computer sound card, some resistors, and a pioneer car power amp along with my handheld DVM. I used the TSparam spreadsheet (googled for it) to do the initial measurements and then I made a spreadsheet to calculate the Vas using the added mass mthod which I found also by googling.
It seems to have worked well except for some small RS drivers that I tried. I am going to try switching one of my stereo receivers for the car amp to see if some weird impedance thing was causing the problem with the little guys.
