You should go with bandpass boxes. Ever see a frequency/power plot of those things? You can design a bandpass box so that it sounds about 20x louder than a sealed box at a given frequency. Just figure out what frequency you are allowed to play and align the box to make a huge peak at that...

Sealed is the safest enclosure for subs. There is always air pressure to control the cone's motion. Playing the sub at loud levels below a ported boxes tuning frequency is likely to destroy it. I tried designing a bandpass box that sounds good and it's pretty much impossible. They're good...

First of all, make sure you know what you're doing. My bet is, once you port this box it's going to be tuned to around 50hz. If that's the case, you can kiss your low end goodbye. It's too easy to make mistakes with ported systems and once you do, you'll get one-note-bass syndrome. My advice...

Yeah, I'll add an option for english/metric.

Yes, I made it from scratch, and you're right, there are a lot of those out already, but few of them are free not to mention platform independent.

Those are called T/S parameter, every woofer has them, they describe the behavior of the sub.

OK I have lots of ideas for this project, this was just something I made yesterday. Eventually I want to create an online subwoofer database with all the t/s parameters and allow users to add their subs. So far it only does sealed boxes but if there's enough interest, I'll do ported and...
