Herman,

I completely do not understand what you ask. The physical aligning of magnets is absolutely irrelevant. The crossover slopes are irrelevant.

OK.

Why would you need to do switching between crossovers slopes?

I want to listen to both 12db/octave and 6db/octave passive versions and see which one sounds better. And keep the one that sounds better.

All that you need to alight is the arrival time of the summits of two sinusoids in the same period. I think the best would be not just tell you how to do it (it was told many times before) but to encourage you to listed your multi-way with and with alignment and to learn what the auditable difference might be.


Let me clarify:

I am trying to move away from my DSP crossover to a passive crossover. Currently I have a DSP crossover @ 2Khz @ 12db/octave.
I will make two versions of the passive crossover: a 12db/octave and 6db/octave version. I have the capacitor and inductor values calculated.
So I need to know when I switch to the passive crossovers, do I also need to re-align the horns?  If so, would you recommend listening to the system and moving one of the channels (lets say the highs because it's easier to move) until the sound becomes coherent?
Then let say I switch the crossover slope, do I have to re-align them again?
The summits must be aligned at the listening position, right?

Herman
