Audio quality: 13" rMBP vs 15" rMBP?

[kathyricks]

Any difference? At Best Buy I noticed the speakers on the 15" are top mounted, but the ambient noise in the store was too loud for me to compare the audio quality.

Don't feel much difference between the two, maybe a minuscule difference exists with the 15" having a slight edge because of speakers top mounted.

Most folks rate the 15" speakers as better than the 13" -- more room for drivers and sound cavities with the wider side panels.

While nowhere near audiophile-level, the 15" sound is actually quite good; the sound is noticeably better that that generated by my 15" late '08 MBP.
