Well, i just wanted to make sure that everything is correct and tbh... checking polarity again doesn't take a lot of time.
More important thing is, that even over a full circle of testing (that's 20 measurements each side in 0.02 steps over the full 0.4ms circle) i couldn't get full summing at the crossover which makes me believe that due to the locations of the drivers it wont happen regardless of what i can do with the DSP amp right now.
I know that Mosconi is currently checking to implement allpass filters into their V1 GUI that is used for the whole Gladen One, Mosconi D2 line of DSP amps as the hardware is officially capable of doing allpass filters according to Frank Miketta, but tbh. i don't really know if this will help me.
edit: i might have a phase issue at 500Hz.
See the left and right and left+right measurement.
That big dip around 500Hz isn't there in either the left or right measurement.
