Terrible sound vibration coming from left side of laptop. G751JT.

This only happens when people are talking (especially present in youtube videos.) I don't notice it in game at all but it is very frustrating b/c I like to listen to videos in the background. I downloaded realtek sound drivers version 7576 and the problem persists. I only recently noticed this problem. What is going on? I'm on windows 10 64bit.

It's the Subwoofer. ;x

Is it possible to fix this?

If the woofers cone is blown, no. if its not seated correctly, you can adjust it or put some rubber dampers in place.
could also be the optic drive, or the exhaust fan.

How can I tell if the cone is blown? I think it might not be seated correctly because I didn't notice the vibration at all until I moved the laptop to clean around it.

Just how.. vibrationy.. are we talking? ;x

Can you pinpoint the vibration location?

Please eject CD tray and hold it in hand, see if vibration persists?

Also, if you have not done so, please reduce BASS levels down to 75% through audio driver (RealTek) or simply reduce BASS depending on driver.
