hello. so, I'm getting a cab built by Don Oatman in the (hopefully) near future. I also bi-amp (two separate outputs, two separate amps), and since I'm starting a bass + drum power duo, I need my bass to be super loud (also, I just want it super loud

). for portability issues, I was looking at getting a physically single cab that contained two cabs that were separated internally and had separate inputs on the back for each half. the top half would be sealed 2x10 + 6.5" + tweeter cab for the highs, and the bottom half would be a ported 2x12 cab for the lows. for the highs, I'm running a Peavey Valveking 100 head, and for the lows, I'm running an SWR Workingman's 4004. but I'm wondering if that would be loud enough. I'm thinking about getting a sealed 4x10 + 6.5" + tweeter for the highs, and a 2x12 (or maybe 3x12) cab for the lows. would anyone have any idea if this would be much louder than the original idea? or would it really not be that much more?
