Hi, I'm new in the speaker DIY world and i'm trying to create my first speaker.
I made a 2-way prototype to learn about measuring drivers and creating crossovers.
In this example i'm using the SB26ADC tweeter in an augerpro waveguide and a NBAC15 5" woofer in a sealed enclosure. Again this prototype is just for testing and learning. I'm planning to add a third way with a 6" NBAC woofer from SB, but that's out of scope right now. I measured the horizontal and vertical axis of both drivers. If I just add an active LR4 high pass/low pass on the tweeter and woofer @2Khz I get the following phase result in vituixcad:
That seems pretty much aligned. However when i create a passive crossover that results in good directivity and on axis response there is a phase mismatch. What are the implications of this mismatch, is it a bad thing? It's a concept I don't understand yet. I gues it's because the slopes are not symmetrical?
