[QUOTE="Team Ampere, post: 7914085, member: 637670"] If you graphed them at 1 cf each sealed, figure out what the rsonant freq of the sealed side would be and then tune the portedc chamber to that. It will normally peak a few hz lower than what its tuned at. 2 sealed and 6 ported would be 3:1. theres alot more to it than just this though [/QUOTE]
