iPhone 8 Stereo Speaker Locations?

Can someone clarify the speaker setup on the 8? Are the two grilles on the bottom the stereo speakers, or is one fake and the earpiece doubles as a stereo speaker? From Apple's product page it's not really clear.

I'm coming from a 6 and am looking forward to more volume from the speakers, and especially a louder earpiece. With my 6 even with the volume all the way up the earpiece on calls is never loud enough or clear enough.

 

Thanks for the fast clarification!
