http://en.wikipedia.org/wiki/Loudspeaker#Terminologyhttp://en.wikipedia.org/wiki/Studio_monitorIt simply relates to the number of speakers present. Two way - Bass driver and tweeter. Three way - Bass driver, tweeter and mid range driver.
The near field and mid field terms relate to the proximity that the speakers are designed for. Near field would be on your desk/meter bridge. Mid field a few feet further away. The output of each being incrementally louder.
The term full range is applied to single speakers designed to play back a wide range of frequencies, like you would normally get in a car or it can refer to a system (of two speakers or more) that plays the full range, so that is a bit confusing.

I'm no expert, but I think that is all correct.
