Here's. 69Hz

Just by looking at these, I think 69Hz seems to be the best. You definitely have some significant room issues going on. You have nulls at 70Hz, 90Hz, and 200 Hz. You have modes at 75Hz, 150Hz and 320Hz (which makes sense since they are related........). But overall, your crossover area seems to be much better and the giant null around 200Hz isn't there anymore so the low midrange should sound much better. The overall frequency range is flatter. There is a lot of 40Hz, but it might actually sound cool and fun with movies, etc. You could use DSP to address these problems by reducing those frequencies that I have mentioned as being room modes along with reducing the 40Hz on the subwoofer. I might have missed this, but do you have DSP in your system?
Also, did you listen to the system with the different crossover points? Was there one that you preferred over the others? Are you able to start hearing the differences in the frequencies that you see on these graphs?
