There the same thing. Just port usally goes by round ports and vent is a coutout. But technically its the same thing. I like vented better. No port whistling.
Oh also, Sean you are wrong. Well not wrong but very vague. You cant just go putting ports everywhere. it dosent work that way, unless you want your sub to sound like trash. You have to carefully tune the port (tune it to where you put it, how long tube etc.) otherwise it wont sound good atall. You can find actual dimensions etc for a tuned box with tuned ports. Follow them or sound bad. End of story. Sean you are a senior member homie. Be more specific. It helps people out more. KK. []Deace homie.
tim i understand very well how porting works although i admit i didnt word my statement clear enough i helped many people build boxes some that hit very hard
It won't really sound any different, the main issue you'll have with either is port noise, which can be fixed quickly by smoothing out the edges and making sure you choose a large enough port area to do the job. Bigger is better in this situation. If you really want to get down to the knitty gritty, slot ports have more friction because of the fact that they're beside an enclosure wall (effectively making the port seem longer, which requires an end correction factor), plus the crossarea ratio which usually is less than ideal (try to keep it under 1:9 ratio of width to height to prevent problems).
speaker displacement is just the amount of airspace taken up by the subwoofer so if said box was 2.00 cf before the sub and the sub took up .25 then you box space would be 1.75 cf and you would design your desired port tune to 1.75 cf instead of 2.00 cf
I kno, sorry it sounded bad. I didnt mean for it to sound like that. Im just sayin some people like it. You kno. Im not quaetioning what you know, or have done, I'm just sayin addin that would be nice. Iet im out for the nite. []Deace
