For those who have been following my crossover thread, I noted that I was going to gut the N8000s and mount the new crossovers to the backs of the existing cases. Pics are included that show how the crossovers were mounted to wooden supports that are then fastened to the chassis. All hardware is brass and the circuit boards stand-offs are copper wire crimps.
BTW, the components in the N8000 are certainly not up to the quality of the components that will replace them. For any that care, the dcr on the two chokes are 2.8 and 2.9 ohms. The crossover also has the 20 ohm resistors across the horn and tweeter outputs and these can't be more than 5 watts' rating tops.
I'll check out the function one more time and give the components a little shot of hot glue to secure them from rattling before final installation.
