2DaMax wanted this so im going to give everyone the url. all you have to put is the driver displacement, size of box, depth of port, size of port, and it will give you the tuning for the box. DO NOT EDIT the tuning frequency box or the box after driver and sub displacement or you will mess up the formulas in the program. the program will tell you what not to edit... i hope you all enjoy this program to help you easly design vented enclosures.

Among sub builders, it's agreed that UniBox is one of the more accurate modeling programs/spreadsheets.
