I have a Monitor 15C that maybe in trouble. This afternoon I was listening to music when a pop ended my enjoyment. I have an Onkyo tx nr616 as the receiver. It gave me a check your speaker wires warning. After some process of elimination I have a speaker that is giving me 3.3 to 3.7 ohms of resistance and I am fearing that is a bad sign. Is there something else that I can check? I love this speaker and am disappointed at this development.
