Thanks Everybody for imput, appreciate it. I had no idea how involved this hobby could truly be. Back to basics, hooked Godzilla to an old pair of advent speakers I had in the basement, the 9090 is fine,. It, I damaged the KG4s, the sound is lacking oomph, a bit muddy. Both of the KG4s sound the same. Do crossover boards fry ???? How do I locate the problem ( blown tweeter, blown board?? ). Again thanks to everybody for help. I think I need bigger Klipsch speakers.
