I haven't had a chance to test the 15" MB Pro but from the looks (maybe deceiving) it seems there is a much larger space both left and right for the speakers. The 2018 MB Pro 13" I have sounds very nice but was curious is anybody who has the 2017-2018 15" notices any difference while it might be "subtle" or "much different" in sound quality and volume.
Cheers!
