the 802's are made to be stacked.. meaning, if u put 2 of the 802 tops together, the sounds is 4x better than 1.. i dont know exactly how it goes, but its somethign like that.. bose is technology, not size... ya know?!?! anyways, bose also makes a sick ass 12" sub.. called the 502CE... and the same goes with the base bins... avanti.. clear isnt the word.. as loud as it goes, u wont hear a ringing sound in your ear after you leave.. i hate it when that happenes! but if your going to do a huge nightclub.. Avalon is the way to be!
