Well, two 10'inch subs have more cone area than one 12 inch sub.
So it's natural that they have higher SPL.
With one driver each ported is higher SPL though.
See my screenshot. WinISD model of both sealed and ported 10w3v3 with 32liters each. Ported is tuned to around 32Hz.
Both simulations have a lowpass BW 18db at 50Hz and both have a highpass at 21db LR24db (to limit excursion below the excursion limit).
Green is ported, blue is sealed. Ported wins down to about 22Hz. ;)
I guess this is the reason that Marc from CAF has chosen a ported box for the blueprint.
Ported is also way less excursion between 50Hz and 25Hz, which means lower distortion.
