I have a pair of JL Audio VR650-csi components. Tweeter, driver and a passive crossover.
I also have an alpine processor H701 which allows me to run them active, which i am currently doing and loving it. (no passive crossover being used)
I was thinking about crossovers, slopes and ranges today and when i went active on my JL's I basically followed the slope settings that the passive crossover was:
1st order low-pass circuit and 3rd order high pass (ie: -6db slope and -18db slope)
What is the benefit of the -6db and -18db slope on these components vs. -12db or -24db?
Because the components are 1st order low-pass circuit and 3rd order high pass, should I have the slope setting between the driver and my sub as -6db or -18db? Or should i have that slope setting -12db or -24db?
So basically to sum it up, I currently have my settings as:
tweeter ==> 4.5khz -18db slope high-pass
driver ==> 4.5khz -6db slope low-pass and 90hz -12db high-pass
Sub ==> 90hz -12db low-pass
Phase at zero for all.
Also should I have my phase set to 180 for any of my speakers because of the slope settings? Should I have my slope settings changed? if so, any reason why? Sorry for the noob questions but I figure if I ask some of the experts i'll get a much better sound in my car.
Please let me know if I'm missing any info in here and I'll include it.
