Datasound - Those are 650z's and LA400s.
The mystery boxes are Carvin 1503's. They need rediculous processing to get them to sound decent. They are mainly used as a PA system for band practice.
Honestly, my favorite thing we have are those little grey yorkville self powered speakers on the left.
I want to get some more but want to hear the qsc hpr112's first. Does anyone have a set of those?
