[QUOTE="T3mpest, post: 7081543, member: 560148"] No he is saying that just because you halve the area you won't actually halve the amount of length needed. If you have 2 ports they will be acoustically summing and nearly acting as one port. If your port is supposed to be 4" wide and 35" deep if you want to do it as 2 2" ports you'll still need probably 30ish inches to keep the overall tuning the same. 2 2" ports with only 17.5 each would be ALOT higher than that single 4. If port cross sectional area remains similar your going to need very similar length overall, you can't cheat it lol. The disadvantage of dual ports is that yes, it is less acoustically effecient. You'll have reduced port noise this way though vs a single port of larger size though. Somtimes if your very close on your port noise and can't fit the extra length using 2 ports is a good compromise. [/QUOTE]
