I've got a 2016 15" Pro, and the right speaker is blown. The top speaker - the one that plays through the grille - still works, but it's incredibly tinny sounding because the bigger speaker pops and stops playing the moment I turn up the volume. Gotta ship it in for service. I've seen a few other posts on the forums with the same issue, so I was curious how much of a problem this is. Who else is having this kind of issue?
