I had a freshly reconed E-120 halfway through the first set ... I bought it on Ebay.
The recone kit was aftermarket -- the paper was black, as opposed to the grey JBL paper.
I don't think you can blow a good E-120 with the factory kit with a 100 watt amp, though. The ones I've had reconed locally (at NE Speaker) with factory kits are taking everything my 800 watt power amp can throw at them. So far, at least.
