Could anyone please provide me the crossover of UM50Pro? I would like to make one for my friend. The configuration shall be 22955+30017*2, but I can't solve the dip of the 30017's mids at 3-4kHz. Thanks!

Are there any crossover recommendation for the following 12-BAs setup? Lows: 2 x 38AJ007 Mids: 3 x 28UAP01 Highs: 1 x 2389 Upper Highs: 30095 Thank you!!!

I know but i just cant open the dx50on the right, it shows nothing on the right side! but there's DX50 and the sdcard on the left hand side.......

I used google translate and i understand a bit, but when I open the app QtADB, it needs me to "choose path to SDK/tools" from file manager, but when i coonect dx50 to my computer and i choose the DX50 (I:) its said theres no adb
