If done correctly, increased power handling and greater maximum SPL. If not, phase cancellation, comb-filter effects, and erratic frequency response depending on listening angle relative to the speaker.
When speakers duplicate drivers
What are the effects of duplicating drivers? I'm not talking about the so-called "half" driver where one does, say, both bass and midrange and the other does only bass, I'm talking about straight duplication.
What is the effect on sound? From a technical standpoint, what happens to the incoming signal when it gets split over duplicate drivers?

. Here’s one with 12 of the same woofers and 9 of the same tweeters in one speaker cabinet. http://www.dagogo.com/gr-research-ls9-loudspeaker-review . |
Done correctly it can work quite well for more power handling. SPL and dynamics- especially bass output. A good example would be two woofers handing off to a midrange driver at a low enough frequency (e.g. 400Hz) where distortion and phase issues are not audible. A 2.5 way can accomplish the same thing. |
