dave_bullet,

I'd like to wire the resistor as you suggested in the following. Would I do this in place of the existing wire between the PCB tweeter + terminal and the tweeter's terminal, or are you suggesting I do this in addition to the existing wire that runs between these two points? Thanks

"PCB tweeter +ve terminal <-> solder a length of wire and crimp an alligator clip <-> teeth of clip onto resistor <-> resistor <-> teeth of second clip and crimp on some wire <-> solder wire to +ve terminal of tweeter"
