Ok, to try and answer some of your responses, I do like my music fairly loud, but I think I exercise enough restraint to keep it out of the danger range. I listen to a wide variety of music. I can be listening to Holly Cole, and next album could be Robin Trower, or perhaps The Beatles or Stones. Just depends on my mood. I tend to not listen to heavy metal or very hard rock ( although I do like these genres), as the recordings tend to be too poor for my liking, so I guess what I'm saying is that nothing too bombastic is playing.
Erik, you have said that the mid range is the unlikely area where the resistors would be blowing, and I agree 100%, but the reality is that this is exactly where the damage always is. This is what has me baffled. I would expect that if I was overpowering the speakers, the tweeter resistors would go south first.
As for the actual testing with my meter, I do have a decent unit that will measure in the mv range, so no problem there. Should I jump the positive/negative with a resistor to simulate a load? If so, what wattage, and because the Wilson's are rated at nom. 4 ohms, should I use a 4 ohm value?
