smilin, if you have the alnico tweeters i'd say you may have blew one. these alnico's blow easy, i lost two in a short time. not sure ,but i think my son blew one with his rap he listens to while i was gone and the other i'm not sure how it got blown, just turned on the system one day and it was that way. i'm not a pro here, but i would agree, the mid's are hard to blow. if the tweets are at fault, you'll need to replace the diaphram, not a hard job. there was a tread on here telling how to do the job. i bought two diaphams and replaced mine and i'm no electrical engineer. all ya have to do is follow directions and do alittle soidering. dave
