Stereo speaker jack as shown
Speaker pointer as shown does not say stereo
The diagram does not say stereo for the speaker at the bottom. If it were Stereo, it would have been announced, pointed to and raved about by Apple.

"The specifications may tell a different tale. Both the Nook HD ($199 on barnesandnoble.com) and Kindle Fire HD ($199 on amazon.com) have better resolution displays than the iPad mini: 1440 x 900 pixels and 1280 x 800 pixels respectively. Furthermore, while the Nook HD offers half the storage capacity of the least capacious iPad mini and of the Kindle Fire HD (16 GB), it is expandable via a built-in microSD card slot, while the iPad mini (like all iPads) and the Kindle Fire HD are not. The Kindle Fire HD also features stereo speakers,
whereas the iPad mini (like all iPads) has a single speaker."
However, since the Mini has a microphone already as shown in top photo, the second picture shows two sets of holes and that leads us to wonder if its two speakers, just not stereo. However, again why did Apple not show two arrows pointing to both sides, not just one pointer to the right side speaker ?
