9to5Mac posts an email exchange with Phil Schiller.
Hi Mr. Schiller,
I understand the tech specs about iPad Mini online should cover everything, but the tech specs online neither confirm or deny the rumors of iPad Mini’s speakers being stereo. Is it possible to get confirmation from the man himself as to whether these are mono or stereo?
Thank you for contributing so much to technology.
It is stereo
The Verge's Joshua Topolsky also confirmed the feature.
People of Earth: Apple confirms iPad mini has STEREO SPEAKERS. As I note in my review.
Reviews of the iPad mini have recently been posted online. You can check out some of them here.
