Location of Speakers on MacBook Pro Retina, 13-inch This sounds obvious, but I've looked all over the internet and haven't been able to find a simple answer telling me where the sound comes out of on a 13-inch Retina MacBook Pro (late 2012). All I can see on the laptop itself are a bunch of vents at the connection between the screen and the keyboard, some longer vents on the left and right sides of the laptop's bottom, and the gaps between the keys themselves. Anyone have a clue?
The speakers on the MacBook Pro 2012 are on the left and right sides between the aluminium case and the battery.  The photos below are of the Macbook Pro bottom case assembly.  The speakers are highlighted in red.
