Thanks for quick comments!

What would be your opinion about the correct crossover?

Am I little worried since I probably need to put sub level 6-8db lower -> dip at 55Hz becomes bigger, and the overall level at 60-140Hz lowers too. I think the reason that pic 5 looks relatively good, is that subwoofer's level is so much higher that main speakers. Because of the it affects to that 55Hz dip and up to 150Hz more than it probably should, considering that I'm currently using 60Hz crossover
