What would ideal port area be for 4 12" L7s tuned to 37hz? I was told about 20 sq. inches per subwoofer for daily. Let me know what you think.

Alright well I'm goin with 122.5" of port area. Bass Box Pro 6 keeps changing my port information when I manually edit the port displacement (BBP6 doesn't know that my port is against the 3 walls) so then I have to change the port displacement when it changes, so it's a never ending cycle obviously. Can someone calculate how deep my port needs to be for 10-10.5 cubes tuned to 37hz with dimensions of 24.5X5? Thanks, someone please respond.
