Want to remove grille from Soundbar but scared!


Hello,
 I have F&D T-180x soundbar (https//www.fendaaudio.com/t180x.html) connected to t.v via aux cable, it's been working fine but from a month ago I noticed very "disturbing shaking sound during high bass/frequency". I then opened it up and tested on laptop as much as I could,and it sounded good, I closed it & attached it again with tv, but after couple of days it again started to give disturbing noise with high frequencies ☹️ I now tried to remove its grille to check if it solves the issue and yes it did!! Soundbar is sounding even much better without grille. But I also came to know that Removing speaker's grille will shorten its life due to sensitive drivers exposed to dust? Please help! I don't know what to do!!! 😥

Thanx.

Thank you all for your response! I really got some helpful tips here.
 
@ebm can you plz explain how it can be bad.
@fuzztone  I'm gonna try changing cable first and give update, although i have tried using optical cable instead of RCA but still had same issue of shaking bass/frequency & with that removing "grille" was the only option which solved the issue, but i will check by replacing RCA now 😀

I appreciate all these valuable responses which cleared some of my misconception! I love this forum!
Thanx!

Yes speaker is somehow affecting & making grille vibrate ,it wasn't like this before i opened the soundbar first time, it happened all of a sudden, may be too much bass/frequency affected grille's balance, and kept increasing, i tested soundbar before with bluetooth & that awful vibration is still there,its not the cable ,its this plastic grille frame which is the issue. Thank you for "White tack" idea! 👍

Thanx!
