I’ve been trying to understand WinISD. A lot say use it, then I read don’t get caught up with the graphs because once you get the sub in “X” vehicle it’ll sound different due to cabin gain so try to choose the flattest response. So here’s a graph for the same 12″ sub but in 3 different size boxes;

Green = Manufacturer recommended size (1.5cuft @ 33Hz)
Orange = WinISD recommended size (4.385cuft. @ 23.62Hz)
Blue = Difference between the two (3cuft @ 30Hz)

At 20Hz the WinISD really shines. At 30Hz the manf’ box drops by 5dB. At 40Hz+ they’re all pretty equal but the blue is closer to the flat response of the WinISD box, so why would someone choose the manf’ box? Is it due to the smaller size so it’ll appeal to more people that might not have the space for a larger box?

Help me understand….
