Would like to make a ported box for 2 subs,but with a single port. I have the specs for the 1 sub/1 vent box. Is the 2 sub/1vent something simple like twice the vent area with the same length,or will the box see that doubled area and the vent have to be made longer to compensate?
ps, the vent will be 100% external from the box.

what are you using to model? Im guessing winISD? If you want more advanced modeling with the ability to accommodate multiple subs and such get BassBox Pro 6. You may have to torrent unless you have the $150 for the program, but it is a phenomenal program.

if you seperate the chambers so that each sub is essentially in its own box, then yes, you will biuld it like it is 2 boxes. if you common chamber them (so they share the airspace) then no. you have to recalculate the port length. a program like BB6 or winISD can help you with it.
