Do a search for WinISD and you can do rather better - a simulation that predicts the response. Oh, and welcome to the forum.

Martin King's sheets are probably the best of the affordable simulators and does some things the pricey ones don't.

The "official" formulas should be around all over the place (ie Brain Steele's diysubwoofers.org, and embedded in UniBox for 2 possibles)

Bassbox is nothing special. Paying for box alignment software is foolish. Save your money for a crossover simulator. BTW - XOPro, by the makers of bassbox, is a total joke. Speaker workshop does more, for no $$ at all.
