I've noticed several cabs available are either 2-way or 3-way cabs. I know the greenboy cabs have the splitter inside the box. Assuming the first cab is 8 0hm, what happens to the signal when a second 8 Ohm cab is attached? Again, since many cabs have two input/outputs on the back, I'm assuming the second cab is connected to the first cab. If the second cab is coming from the amp, then it is getting all of the signal. All this is assuming the splitter is IN THE CAB. Does the sub get all of the signal even though it might only use 40hz - 800hz?
