Subwoofer.Tools is a free to use subwoofer box calculator. For a given woofer and box, the website will return a panel layout, frequency response and a cut sheet. box calculator The graphic display is intended as a way to visualize some of the proportions as you manipulate the size of the box. Currently, its maximum size for display is 35' x 16' x 18'. The very first version of Subwoofer Simulator was a basic Vented-Box calculator compiled in one little MS-DOS command-line utility. The MS-DOS executable file used equations from Ray Alden's book, 'Advanced Speaker Design for the Hobbyist and Technician.' The utility simply calculated net enclosure volumes and port dimensions off one 'alignment'.
