Greetings. The midrange speakers on one of my M22s have started to cut on and off. I tried rapping it with my knuckle once and the sound returned briefly. I'm "handy" but not familiar with speaker circuitry, so I don't know if this might be the proverbial loose wire or something more difficult. How should I investigate? Thanks for any suggestions.
