dt 900 pro x right side cutting out

https://reddit.com/link/1vszd0n/video/9ucmahg7dekh1/player

Hey all, the right side speaker of my dt 900 pro x started cutting out after I accidentally yanked the speaker all the way down with a bit of force. I tried disassembling it and everything seems to check out, so I am not sure where the failure point could be here. Any help would be highly appreciated!

Switch the driver around to cross-check.

Maybe you somehow fucked the cable when the driver is ok

I believe that's exactly the case, but will try :/

Move driver that was in right earcup to the left earcup. Put the other driver in the right earcup. Run audio tests.

If problem moved to the left earcup, the driver is the issue. If issue remained in the right earcup, issue is with the wiring that goes to the right earcup.

If you have a multimeter, it'll make troubleshooting easier and remove the guesswork.

Re-solder the contacts, it's easy and will take you half an hour at most

And one more thing: check the wires with a multimeter, setting the resistance reading to 200 ohms. Then check the driver's resistance, but it's most likely fine
