Correct me if I'm wrong, but isn't it theoretically about a 3db gain every time you double wattage? If so, I think you're good up until you add the 3rd VC. At that point, I would think it should go from a 300w gain to a 600w gain for a 3db gain, right? So it should go 2nd VC- 300w: 113db, then 3rd/4th VC- 600w: 116db. Or, are you compensating for the 2nd woofer's cone area? I don't know that much about it... everything else sounds good. That was the only thing that sounded off to me.
