Aero Port!?!?! Help lol

I have a duel 12 square sealed enclosure each sub has an air space of 0.93 cu.... Can I aero port this????? I've been told no then I found this port calculator on this site

http://www.psp-inc.com/tools.html

And basically it's telling me I can tune my box with a 3" aero port that's about 12 inches long at 40hz.... Any box guru's on here than could verify and credit this calculation tool???!?!?

Please and thank you

 

I have no doubts on the correctness of that tool, but will it sound good is another question. In almost every single case, going from sealed to a properly ported enclosure requires a larger enclosure. So you can't just take a sealed enclosure, throw a port on it, and expect the same subwoofer to hit harder and lower. You're defying the laws of physics if you expect that to happen.

Typically subwoofer manufacturers will spec a recommend ported enclosure that includes box volume, port area, and length. If you don't have manufacturer numbers, then you need to use one of the many box design calculators available. WinISD, unibox, and BassBox Pro are some of the more reliable software tools.

 

I have to agree with ike3000 on this one. Find a box building program you like, and put the parameters in it. Making a port in my box, would have required a port of 25" long, there's just physically not enough space in there to jam 25" of 4" port in the box. So that's why I went sealed. I could have gone with one sub, but I had two, and wanted to use 2.

 

These subs are already in an enclosure that's too small for them sealed...

What if I used really large ports and mounted externally? That would add cubes to my box then maybe stuff it with poly
