In Reply to: Port variation for doubled woofer posted by DRCope on January 03, 2003 at 18:08:29:

To put two of the same woofer in a cabinet, you can basically double the volume and tune the port to the appropriate frequency using Helmholtz formula. You will find that PiAlign is able to do this for you by simply entering a value of "2" in qty instead of "1."
