Hey everone, I have a question regarding the rMBP (haswell) built-in loudspeakers.. Is there any possibility that my loudspeakers could be calibrated too loud or 'too much' bass or something? When I play a song (or any youtube vid) on the 4th or 5th volumebar, I usually feel the body of the macbook pro 'vibrating' when my hand palms are resting on the mbp. To be clear, I dont hear any rattling sound (so that probably clears out that there is something too loose in my mbp). Anyone has an idea about this? Probably best way is to check out a rMBP at a store to make sure this 'behaviour' is normal, but in Belgium we dont have an Apple store and other retailers mostly have last year model on their display shelfs.. ps "dont let your palms rest on the mbp" aint a solution, since im writing my dissertation and requires alot of text processing hours Thanks ahead!
