Lightbulb Formulas and Program

Hello!

My name is Vladimir and I am from Ukraine. My hobby is DIY audio.
I have a question about formulas to calculate subwoofer.
Some of them I find here http://www.diysubwoofers.org/
and (I want to create a program like JBL SS,BassBox)
but with it I can plot only Frequency response graph and Power Response, also I want find formulas to able plot more graph(like Group Delay, Cone Excursion etc.)

I would really appreciate If some of you can help me to it.

Also I have already create a scratch version of my program, pls see it here http://rghost.ru/415196 (if it will not plot any change value "," to "." coma to dot) and do not worry about "??????" in text labels, the program will be in eng and rus languages, I will fix all in newest versions. For now, I do not have much time for it.

Thank you in advance.

P.S. Sorry for bad English.

Buy a book, "Theory and Design of Loudspeaker Enclosures" by J.E. Benson, or go to library.

You can also look for Thiele and Small's JAES articles. Another Resource may be "Bullock on Boxes", a very inexpensive book. How well you can make these sources work depends on your mathematical aptitude. Good luck.
