So I'm new to the game of speaker building, I tried an MTM design with Dayton Audio drivers using their in house frequency response measurements, in classic style, I built before I read. I'm going back to the drawing board for MKII design, what I need to know is order of operations. So I have the driver's, once the cabinet is assembled would I then take FR's of each driver to load in to vituixcad to design the crossover? As I now believe the ones supplied Dayton audio obviously wouldn't match the cabinet I've built. Also, would you measure both Mids together as single response graph? And when measuring, would you just discount the tweeter to measure the mids and vice versa for the tweeters? I'm sure this has been discussed before but there's some many posts at this point, the digging wearing me down.
When measuring both together, would the microphone placement be directed around the tweeter for a balanced response?
Sure. People talk about what centre point to use to rotate the axial measurements, but if you take enough measurements it begins to not matter. Of course there is no one point with a line source but it would be typical to choose the tweeter baffle location to work with.
I made a response to a very similar question a few months ago. You may find this useful.
