I have 2 jbl 2441 compression drivers that need to be remagnitized but don't know where to turn! both drivers are disassembled so I can install new throats that damaged when they were sent to me.my main question is do the drivers have to be fully assembled, including diaphragms, to be remagnitized? Bill at GPA wasn't much help when I talked a few weeks back, he mentioned about diaphragm gap etc, but that was about it! Maybe I didn't ask the right questions. I'm still searching for places to recharge them, but I'm not done yet. I'm up here in mich just outside Detroit if theres someplace within driving distance would be great! any help is appreciated jake
