Hi
Since yesterday I have a strange vibration sounds on my 4430 right boomer. I made a test and this vibration sounds is between 432 & 542 hz...
I used the 4430 heavily those last day with techno at high volume without audible saturation.
I've send the 2 boomers for restoration 4 month ago... They look brand new and sounds really good!
Can I repair this kind of problem myself? What can I do?
Thank you!
