Speaker replacement made sound even worse!
I got a question about a speaker replacement in the 15” MacBook Pro Touch Bar 2016.
Recently I replaced them for a customer of mine. I ordered a set speakers from China (I'm sure they're original).
Because the left speaker didn't sound as good as the right speaker. I thought it would be an easy job, but it was a huge mistake. Apparently the speakers in this system are held down with strong adhesive. VERY strong adhesive!!
You can compare it with the adhesive underneath the iPhone batteries. So it took me a hour to get both speakers out (I replaced the right speaker also, to be sure there would be no difference between the left and right).
I did get the speakers out without damaging them, and I replaced them with the new ones, and put tesa tape underneath them. I thought, well easy job. I turned the MacBook Pro on. Only the sound by low tones and bass is horrible (you can hear it obvious in the video)
It sounds like something has loosen in the speakers.
So I put back the old ones, thinking it would be the new speakers themselves that just aren't good enough. But then the sound was also worse and exactly the same as the new ones. So maybe it was the way I assembled the speakers in the system. I putted a lot of tesa tape, 2 layers!!, under the speakers but that also didn't help. I really don't know what to do right now.
Does anyone recognize this problem?
you can fix all this by reverting to OSX Lion and changing the date back to when you where covered by the warranty.
