I just purchased a new MacBook Pro Unibody 15" (summer 2009). I'm comparing it to a MacBook Pro Unibody 15" (late 2008) model. The speakers on the older one seem to sound louder and more clear to my untrained ear.
Is there any way I can confirm this for sure? Is there any software that can measure the output of the speakers and tell me which one is louder? If not, how should I go about figuring this out. I think the difference is too subtle to be able to take to the Apple Store without having any reasonable evidence in my hand.
