The iPhone 4S only has one speaker. This speaker is located on the right hand side of the iPhone, as it is facing you, close to the dock connector. There are two microphones on the iPhone, one by the dock and one next to the headphone jack which are sometimes mistaken for speakers, but are actually microphones.
