I've had my MM120s for about 2 months now, and loved them until recently! I was just listening to music as usual one night and then my bass was gone! I got home later took them out of the box and the positive terminal connects and the wire leading to the voice coil came appart. Now I have no idea what to do. I didn't buy them from a dealer, I got them online. I am so upset! If someone could help, much would be appreicated. THANKS!
