For the life of me I can't figure out how to get WinISD to model SPL or cone excursion.
You need the Sd for that, it's not listed so use 800 cm2 which is about right for a 15 inch sub. Modeling shows 2 subs in 12 cu.ft. tuned to 18 hz looks good. Input power is 1200 watts with a high pass filter at 15 hz to prevent over excursion. Porting would be a 8 inch diameter tube 29 inches long to keep the port air speed at 27 m/s.
