Well, I was having a house party last night when out of nowhere I smell something burning. Being that all the stereo equipment was mine I immediately rushed over to the receiver and where everything is plugged in at. Nothing going on there, then I take a look over to one of my speakers and what do you know, the bloody thing is on fire. Literally on fire! I was so shocked. Theirs nothing near the speaker that would cause this, and after ripping the grill off and extinguishing that, I see that the cone is on fire. That took a while to get out, but my question is, has anybody heard of anything happening like this before? The speaker is done for, and I don't really mind too much, I had a backup pair to finish out the party with and they were free (pair of MTX AAL 1240). It was just wild to look over and see my speaker on fire. I would post a pic of the damage to the speaker, but being that it burned through about 35% of the cone, some of the party goers decided to have a little fun with the "trash" :/
EDIT: I should probably also ask if you guys have any ideas as to what may have caused this. I am using pretty old speaker wire, but my first assumption would be internal problems.
