Just curious if any of you mix crossover slopes for your active setups. I'm currently trying to eliminate some bad peaks right around 3k and decided to use some different crossover slopes. Currently when I'm on 4th order, crossed over at 2.5-3k with my RS100's, I get major peaks that I can't EQ out. I decided a 2nd order was, well, in order (no pun intended). I crossed the 2nd order over right around 2-2.5k and it definitely smoothed out the response.
If I'm going with a 2nd order, how much more should I drop my crossover? I was running the 4th orders at 2.75KHz for the midrange and 3KHz for the tweeter. Now I'm running 2nd order for the midrange @ 2KHz and 4th order for the tweeter @ 3KHz. Is this a logical point for said drivers/x-overs?
Also, is it common practice to mix 2nd and 4th orders like this? What advantages or disadvantages could arise from it?
