For djing though.. I don’t see the crossover to mixing in 5.1 anytime soon. It does not work in the club environment... only in the theater environment.

2 problems..

-Speakers across the room pointed back towards the dj will result in a sound delay. It’s totally against the wall of sound standard layout and a nightmare to mix.

-Surround sound is meant for a center audience. In a club people are everywhere, and 'joe blow' over by the far left speaker will only hear a percussion wizz with the lead synth coming from way across the room. (for example)
