[QUOTE="bigbang, post: 3303513, member: 576408"] OK, two 4" ports, one 6" port. 2squared=4 2squared=4 3squared=9 Ratio of volume of box tuned to each port is 4:4:9 So just saying you had 1.7cubic feet of volume after displacement, each 4" port would be tuned to 0.40cubic feet, and the 6: port would be tuned to 0.90cubic feet. This is my theory of how you would go about tuning the different ports so that each one would be tuned by a certain volume proportional to it's own port area. And of course they are all tuned to the same frequency. Someone correct me if I am mistaken. [/QUOTE]
