QUESTIONS:

1. What crossover frequencies are folks using for car audio 2-way component systems in an active setup using 1-inch tweeters and 6-1/2 inch drivers? Are you high pass filtering the tweeter at about 2 kHz?
2. What slopes are you using for the different drivers? Would this be appropriate:

I bought a pair of Focal ISS 165 component speakers on sale. The crossover is integrated into the speaker wire, but I plan to use the drivers in an active crossover configuration. I removed the heat shrink from the speaker wire to obtain the RC values:

R = 4.7 Ohms

C = 3.3 micro-F


The corresponding cutoff frequency for these values should be fc = 10 kHz.


I have been out of audio for some time, but I am used to home audio 2-way speakers having a cross over frequency around 2 kHz, not 10 kHz.


I have reached out to Focal but they have not responded.

All depends on the tweeter and it's resonant frequency. Any data sheets on the speakers?

Not really a big fan of focal as their adhesives used in their tweeters were quite lacking in the automotive environment.
