Question about JBL Music
The speakers are rated 250 Watts. Driving with 600 Watt amps requires one to be careful of how much the volume is turned up to avoid damage. You MAY have damaged more than just the compression drivers on the horns but the voice coils on the 15 inch speakers as well. Further use could also damage the amplifiers. You did not mention what brand amps and it is possible they have a problem.
You best replace the units with ones rated for the power of the amps as restoring them on short notice for a gig is not practical.
