For starters, I followed David Brancato's videos. Because of the detail and the length, I made a step by step list of things to do. It ended up being four pages long and I used that for my first test.
I have a set of speakers I built using a kit from Parts Express.
The main question I have relates to phase. I used rePhase and then created the FIR filters. I have a QSC Core 250 that is handling the processing. One difference between the video and what I did is that I set the taps to 1024 to keep the delay to around 10ms. The initial phase trace wasn't terrible. But when I did a final measurement after adding in the FIR filter, the phase wrapped around 100 times. That wasn't expected and I'm sure I did something wrong. Pictures below of the initial measurement, the predicted result, and the final measurement.
Initial (7 position average)
Predicted
Actual measurement with FIR filters
Because I'm new I can't post a link to my instructions or the video
