I'm currently working on an enclosure and found only a couple specs on my sub. Was just wondering how this numbers play out on a vent?



small 2ft (F/33.31Hz - Fb/31.21Hz) vent = 5"x13.41"
large 2.5ft (F/30.2Hz - Fb/29.44Hz) vent = 4"x11.65"


Does that represent a slot or round port?

odd they tell you to go with a smaller port for the larger box
