2 track. It was a cool room, but the omni directional speakers arent my cup of tea so the room was just ok sounding IMO.

The YG's I think were my favorite over all sound, but the Sanders room was very nice and the Odessey room was outstanding as well. I also dug the Wilsons, but considering the expense vs the Odessey and Sanders systems it just wasnt that great....not 15-20x better for sure!
