this is probably gunna sound dumb but when designing a port for a box do you use the amount of airspace thats in the box before the port is added or the desired amount of airspace in order to find the amount of port area you need? also how long should the port be if i want to tune the box to 33hz....my desired net is 8.8-9 cubes..thank you

desired airspace. the port will take up airspace, this should not be included in the final airspace.

port length will depend on the size of the port also, not just the size of the enclosure.

you may want to list the subs in question and we can better help you with this.

might be worth the 5-10$ itll cost you to have someone design one for you. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

naw i dont want any autocad drawing lol...i just need little pieces of info to put together.... and i have 4 aq hdc3s on a 3500d.1.... aq said 8.8 cubes is ideal for this setup so that should definitely work

they want you to have 8.8 net not gross tho... that means closer to 10+ cf. gross...

you should have more than enough room ( u have 14+ cf...)

If you can get 13.75ft^3 then do 160in^2 port area around 29in long. Then do proper bracing and 45s. After all displacements it should put you right about were you need to be for these subs which is in the 10ft^3 area after all displacements.
