So i went to this really expensive speaker store, not to buy just to listen.

But one Subwoofer SOUNDED MASSIVE, so i aked him why because it was just a 9in cube.

He said that there were 4 speakers in it, but only 1 speaker was active.

So the 1 active speaker moved in and out creating air pressure, and that moved the other 3 speakers, making the speakers efficient and extremely loud for the size.
 
Check out Boston Acoustics Kyle... This is not new stuff...

It's called Passive Radiator Technology.
