The 2.21" says 806 type driver. I can't find my calipers, but a tape measure confirmed that.
So next question is the phase plug. Just use a flashlight in the throat....remove it from the horn....and tell us if it's silver or orange.

Then be sure to measure the resistance to make sure it's not dead.

Alwaws fun to remove the frams and get the part number....but if you haven't done it, you can damage them pretty easy.

If you want to try, I'll give you my procedure.

These odball 806's of mine have the desired 23744 lightweight frams and the tangerine phase plugs.

And yeah, these have been sitting in my living room half assembled for 6 months now. I just need to remove one bug screen, put them together and haul em down to the audio room.

It's hot rod season. Headed out the the garage to Chop, Cut, Rebuild.......and weld!
