so excluding one tweeter what we see is that your door mids work best when out of phase with the rest of the system. As I recall you have them angled in the door panel right?

Are you calibrating with the MS-8 after you do these phase swaps? I remember Andy saying the MS-8 does not check phase, it just assumes everything is in phase and then does time alignment and EQ and that pretty much corrects everything anyway.....but if something is out of phase it may have a lot of work to do do correct it, and even then it will only be possible to a point....

Also with regards to phase...Im wondering also if the phase of your mids is not inadvertently swapped somewhere (like in the amp or the speakers themselves), Im wondering if you checked phase to each channel individually if you would not find the mids were backwards... Or maybe its the angle, on axis vs. off axis....

Trying to get my head around how the MS-8 is working with what you are doing.


As a separate point....back in the old days (pre DSPs), the beginning of any high end system started with playing with speaker placement, angles, and phase, trying to get image and tonality "naturally" as close to perfect as we could, before we started playing with delays and EQ. Now days DSPs mask a lot of this as they auto correct for a lot, but makes me wonder if there isnt something being left on the table....
