Since at TC Sounds' website they have "NA" marked for ported boxes, and at SI's site they have 3.5^3 marked, do you think that the TC Sounds or the SI box needs more space? And how much do you think is needed for the TC3000?
well you use the passive radioter volume for ported. tc sounds didnt think it was practical to have ported volumes because there sq based subs and the port lengths will exceed 50 inches in almost every case.
