I'd look into having it re-coned. Probably a bit cheaper than all new driver. I see places advertised all over the Bay area for this. Take a look on your local Craigslist and I bet you'll find someone. Or, find a nice high end shop and ask for a referral for a repair shop.
Well, since you fired the first JBL salvo, I gotta return fire with some vintage Klipsch, LOL

I just brought three of these big boys home this evening. Got Sarah McLachlan flowin like warm butter.

The third isn't shown. I'll probably sell it off. To big for my use as a center. The slanted Heresys on the ends were my mains. They will become my sides. I've also got another pair of Heresys that are like the big Corns (Decorators) that I need to strip off a cheesy black paint job then I'll refinish them to match. I might use them to build a custom center though. In the future I might try my hand at a custom veneer on the Decorator cabs..
Course now I have to rearrange some furniture to get a decent soundstage again. I'll probably end up using the whole back wall.
