So I was playing some songs through my new 2016 Macbook and noticed that the right speaker driver tends to distort and produce a tinny rattling sound when the lower frequencies come up. This happens from anything beyond 60% speaker volume. I tried covering the keyboard keys to ensure that the rattling wasn't produced by the keys shaking around, but the rattling still occurs. Is this normal? I can play full volume on my iPad Pro 12.9" and the speakers hold up just fine. Now if this is indeed a problem with my MB speakers, how will Apple fix the issue? Would I have to send my MB in for a repair or could they do an exchange? Problem is my unit is the m7 so its not like I can just grab one off the shelves? Has anyone else had this issue with their Macbook speakers?
