There was no call for you to make that snotty remark. The OP's usage of
terms impedance, and resistance were correct, and appropriate. His
measurement of the DC resistance was also an appropriate thing to do.

For one thing, it tells him that the impedance of the transformer must
be greater, much greater than the 470 ohms he measured. 5K would be
about right.

Just go with whatever connection sounds the best and produces the loudest
output out of the speaker.

The impedance of the raw speaker is most likely 8-ohms.

the input impedance of this mystery xfmr? When hooked to my SX 28A, the 5K
terminals had more clarity in the sound than the 500 ohm terminals (which
sounded more bassy). Just for the heck of it I measured the input

resistance

and got 470 ohms.
