when i make enclosures all can make is sealed enclosures. but id like to start and learn how to make a ported enclosure. i kno theres alot that goes into making these awsome boxes. i want to know how do u kno where walls should go and how big ports should be. and basic stuff like that. this is my first ported box. i got a 10" jl w0 in a sealed box that im not using and wanna make a ported box for that. sounds great but i wanna learn how to make ported enclosures. so how do u do it without guessing? thanks.

Head to JL's site; they have some great information on these things.

It's almost as simple as a sealed enclosure, but you have to figure in your vent size, tuning frequency, length, etc. . .

Do a google search and you'll find tons of good information. I would write something up here, but it would literally take all day.

oh ok. thanks. imma do sum research.

Google subwoofer math a lot of good sites will come up, an good luck.

I use the modeling program winISD. You can easily manipulate the port, enclosure size, etc., to see how the port dimensions and tuning change.

the help files in WinISD have alot of useful info!
