You don't understand how crossovers work. The other components in a crossover (besides the speakers themselves), all work together to provide a nominal impedance to your amplifier. It's part of the design... When you measure the inputs terminals of a speaker system, you are measuring DCR, the DC resistance of the entire network as designed. The impedance listed, let's say 8 ohms, will actually vary depending on the frequency of the signal being fed to it from your amplifier. Some speakers can drop down to 2 ohms. This is why many amps can't be used with two pairs of speaker systems at the same time, as the load (impedance) drops too low, and the amp can't provide enough current.
As was stated above, the best thing is to call Klipsch and find out what is supposed to be in those cabinets and see what the cost to replace/fix with correct parts will cost you. There are some knowledgeable people on here, who might be able to help, if you live close to one of them.

Hey man i appreciate your advice here. I do know how crossovers work. they split a full spectrum signal into appropriate frequencies for a given speaker. What did i write above that made me seem ignorant? I was referring to the fact that yes, eventhough a X/O may change the Ohms, my tweeter is stamped 3 ohm and it will read three ohm at one side of the X/O and an open circuit on the other end where it should be giving some SOME measure of ohms, eventhough maybe not three ohms, there isnt continuity in the crossover board. Hope that explains it better and thanks for your help
