07denali Posted April 22, 2012 Report Share Posted April 22, 2012 The length of your port is deeper than the depth of the box 22 vs 30. I think your calculation might be off unless I made a mistake.

07denali Posted April 22, 2012 Report Share Posted April 22, 2012 Nm. I guess you are doing a side port rather than a front port like I designed.

Kiean123 Posted April 22, 2012 Report Share Posted April 22, 2012 how do you get the frequency a bit lower/higher? which number do you change? Quote wooohoo! -Acura RL 2005.

Joe X Posted April 22, 2012 Report Share Posted April 22, 2012 There are many ways to change the tuning frequency, changing the width of the port, the length or simply changing the size of the box. any changes will have an overall effect on the box performance so do it with care or ask for a different tuning.
