I searched and didn't see this, I own an Ampeg 4x10. I am going to add another cab with my Eden WT-800 head. I like the idea of a 15 a lot, but I was considering adding another 4x10 and running a stereo set up on stage having one cab at each end of the stage. I know it would sound sweet. But the full range sound of adding a 15 is also very appealing but this would rule out the stereo concept. Has anyone used the stereo concept before around here? I guess the optimal way to go is pick up a used 4 x10 and a 15' and depending on the club have the option for both set ups but who has that kind of cash laying around, any thoughts?
