Port size and frequency

[Drek75633]

Say I have a 11.5 cubic foot box. And I wanted an open port such as steve meade runs. How big would I make the port and how long if I wanted a 30 hz solid port and a 40 hz removable port?

Well if thats 11.5 cubes AFTER displacments (subs bracing etc) Then just use RE Box Calculator and thatll give you the port specs you need. But if its before displacments then use ExpoSports box calc. Its really easy to use. Hope this helps
