I'm glad to hear that your activation does work. I believe that removing passive crossover improves the sound in most of cases.
Doing 3 way crossover I would start with activating bass. Just remove passive crossover from the bass and do 3rd order active crossover with previously said calculations. Then after that I would try to remove 3rd order high pass from the mid and do also that with Devialet. And the best results you will get to have acoustic measurements and do the fine tuning of delays. All this you can do without help from Devialet. But then the 3 way crossover. You can send the crossover point information to Devialet and see how they are doing it, actually I'm quite sure they are doing it wrong... but would like to see if how they do it.
