I know it sounds like something from KFC,but it really happened,i bought an ashdown mag 300 watt combo(second hand)at the end of last year,the first time i got to use it in a gig situation was last week,a few songs later,smoke started coming out of the port holes at the back of the amp,behind the speaker,the singer thought the smoke effect was great,but i launched the amp outside,i thought the thing was going up in flames,got it back in the pub and put the amp through a spare 4 X 10 cabinet,and all was well,anyway,got it home and stripped the speaker out,turned out to be a 180 watt 8 ohm speaker,the amp has a 4ohm output,there was no burnt wires,but the speaker did have a dodgy smell from behind the cone and has no life in it at all now.Can anyone back up my theory that it was the compleatly wrong speaker,or should that speaker be able to handle the amp,it being 8ohms and all,......thanks for any help,cheers
