I am glad you are entertained, I am learning a lot, I admit that I hate just being told to trust the design I like to hear the how and why too, I appreciate the support and input of everyone who comments. Thank you all!!!
I do have a question I would like to pose that I am interested to see what I get back. I believe that as I mess with my driverack the crossover in particular I believe that adjusting the filter order or slope of one filter that the phase alligmnet changes! I find my self having to change polarity often after adjusting the filter slope or order in order to get the drivers back in coincidence. Am I crazy or is this a thing? Thank you guys in advance!
Regarding your driverack and changing settings:
What you are experiencing is no surprise.
Phase is frequency dependant.
So when you change the frequency of the crossover point, you should expect a change in phase, leading to the correction you have noticed.
Then add in altering slope (and slope type). Since slopes are X dB/octave, they affect phase in the frequencies around the crossover point as well.
It's beyond most of us as small time operators to afford (or justify buying) the measuring equipment to test phase.
That's why, the best advice usually seen here, and the simplest thing to do, is to make sure the subs and tops/mains are in phase at the crossover point, every time you setup.
If you have phase altering capability in your DSP, then you can see if either the subs or tops are out of phase with each other at the crossover point by phase shifting by 180 degrees, and if it was out of phase, it will now get louder at the crossover frequency.
You can also make up a phase test speaker lead (it should be marked as that btw), with one plug on the lead having polarity swapped to do the same thing...
