For tweeters, they say to take the resonant frequency and multiply that by 2.5x, and that figure should be the lowest you should cross your tweeter over. The resonant frequency of my desired tweeter is exactly 1,520hz. If you do the math, that's 3,800hz.
Why is this?
Is a 3.8khz crossover point the absolute lowest my tweeter will be able to cross at the lowest possible slope, which would be a 6dB/octave? I understand I can cross lower if I'm using a steeper slope, but I just want to make sure this is correct.
Also, that mid-woofer plays relatively flat up to about 5khz with the exception of that little peak. If I wire a 10uF poly cap in series with my tweeter giving me a x-over point of 3.8khz at 6dB/octave, then where should I cross my mid-woofer over? Should I overlap? How much?Do you guys think it would be better to cross with a steeper slope on my tweeter or just use a notch filter on the mid-woofer? I really don't want my mid-woofer playing past 3khz because of the peak at 5khz. However, I'd be breaking rules if I crossed my tweeter under 3.8khz.
