Hello all, I put a dent in my LS50 - a significant dent that causes a bit of fuzz - see picture . Since it's a uni-driver - seems that the midrange is now touching the tweeter. (while this design supposedly sounds better - sure puts 'all your eggs in one basket') Don't want to spend $400 just replacing the cone and I'm sure you can not re-cone them like in olden days. So there is nothing to lose in trying to fix: hair dryer to heat metal, push in from back, or is there a way to re-cone aluminum. Thanks for your advice and I'll let you know how it goes on the forum.
