Call me crazy but...
After my IT01 left side driver flex evolving worse (not caused by modifications) and cable sleeving material gone hard and springy....
...I opened them up again and took out drivers by "brute force" as I didn`t care for those anymore. RIP IT01 and thanks for filling my ears with fun sound.
What I discovered was - right under driver shell (helmholz resonator) there`s little fabric venting filter as expected... but... driver shell is installed in a way that it
literally presses against that filter and that caused bad air-flow (and thus driver flex).
IMHO this is pure design fault as many IT01 owners have driver flex issue.
WHY o why I removed drivers and didn`t re-sell them or something?
Well, I need nice shells for my VE BIE drivers and they fit like a glove and I like my modification looks
Will post pics later tonight if I can.
Peace and don`t hate me for destroying IT01 !
