That would be completely wack. Firstly they would have to be exactly the same speakers and have around the same amount of use. Secondly, you're gonna have two identical signals coming at your left ear, and unless you possition them perfectly, I'd imagine that would create a whole bunch of phasing issues. Its a pretty un-ideal setup anywhos man, read/look at this. http://www.soundonsound.com/sos/mar02/a ... nitors.asp
