[QUOTE="Immacomputer, post: 2781359, member: 570419"] With it like you have it, it will probably be in the low 30s. Test the sub's excursion with test tones and try to find the frequency where the sub seems to move the least. This will give you an idea where it's tuned. You may have a little more length than you think though. Hopefully you won't have much port noise and it sounds nice. Something else to think about: It looks from the original design that you didn't leave enough space behind the port wall. Make sure to keep the port panel at least the port's width away from the back wall. I think you only had a little over 3" of clearance behind the port wall but your port width was 4". Try to keep it like design "B" in the picture here and not like design "A": [IMG]http://i10.tinypic.com/2qjjgc8.png[/IMG] [/QUOTE]
