hi alex, i run a sound system company back home. if i can find the parts, i would be able to recone/repair them.

the other thing is, take out the HF horn and check for dry joints on the crossover and/or sometimes the cable clip slides off. They could be fine!

being hoenst with you. its an entry level JBL speaker and i can recommend drivers that will be able to perform the same if not better for the same price. Best part is that they will be readily available as JBL parts can be a bugger to find.

PM me.
