I'm building a 214L vented box with a 15" tempest ( http://www.adireaudio.com/Files/TempestTechSummary.PDF )

I have 3" dual flared ports ready to be cut but I can't figure out how to calculate the lenght for 2 ports. I want to tune it to 15.4 hz. Thanks for the help.

When using more than one port, divide your box volume by the number of ports you want to use in the formula.
