Can many small, quieter speakers produce sound equivalent to a single larger, louder speaker?

Say I have 200 phones playing a song, does the volume increase when coming from many sources?

Yes, due to a principle called constructive interference, the sound waves with matching and in phase frequencies will build on eachother, making the amplitude higher and the volume louder. 
Think of a crowd cheering in a stadium for a simple example.

However, from an engineering point of view the sound would probably sound distorted unless you were listening in an open field, or the small speakers were very close together. This is because the holes you see in speakers are designed to 'spread' the sound out, and with multiple different speakers the waves could reach you at different times causing a very slightly dodgy sound (this may well be an insignificantly small error however)
