I could be wrong, we might be feeding the same signal to both stacks.
It sounds great, anyway.
I was gonna say, you might as well just run mono, and concentrate on getting the crossovers set up just right, and the eq perfect, than dealing with stereo.
You`ll get more efficiency out of the amps too.
Solitary by nature.
Isolation is the gift.
Does anyone have courage to stand apart any more?
