I bought a house a few years ago and found 6 jbl pro series 2245h speakers that need reconing . I consulted a few locals and decided to gut the baskets and prep them for reconing . I taped the voice coil gap on each after using an air chuck to blow them out . The last one i completed was sitting on the table in my shop . My son went in to play his drums , needless to say i picked the basket off of the floor to find that my voice coil gap was closed in on one side . can i use a brass punch and rubber mallet to center my gap again or is this basket ruined for good . HELP !!!
