Does this speaker contain one or two speakers? Is it a true stereo speaker or is it mono?
Two front 2-1/2" speakers. Also designed to bounce more of the bass sound out of two small 1" ports from rear of unit. Yes you are getting stereo out of a left & right speaker and it does a fair job at filling a small room with sound. However you are not going to get the type of stereo sound you would from two speakers that are 10-14 feet apart with an amplifier putting out 20-50 watts per channel. But it's fine for a use like in the advertising photo shown.
