Re: Repairing Alesis M1 Active mk2 Monitor Speakers

Hi All,

I've actually followed the advice on this forum to repair one of my units previously (replaced C8 with a low ESR Panasonic and the resistor nearby due to charring). I also stood off the cap to move it away from the heat a little.

The speaker in question is a spare 3rd one I have and I went to use it today and found it not to work properly anymore. The LED lights, tweeter works fine, but no woofer.

I have done lots of voltage testing and everything is in spec. The PSU is outputting...
