Thanks Alan for your suggestion to get the resistors for my M60, I just installed them and FOR ME it made a big difference!, now I found my M60 sound really 'SWEET'. It was a very simple installation, you can’t do wrong. Tho, I was not sure what happens if the resistor's clip or wire make contact with the tweeter magnet so I cover the whole resistor, wire & clips with electrical black tape just in case.
