New member Username: FullergokuNorth Carolina United States Post Number: 1 Registered: Sep-05 | I'm thinking of purchasing either a DD 9512 or DD 3512 but I've never built a ported box. The space I have is 28w x 25H x 9.75D and I want to tune the box to 30 can some one help me with the port size and length?? |

New member Username: FullergokuNorth Carolina United States Post Number: 4 Registered: Sep-05 | That isn't enough room for 9512 or 3512?? It's right at 3 cubs before sub displacement. On their website I thnk I remember them saying anything over 2 cubic ft was fine. How would this effect the sub in a 2.75 cubic ft. box?? |

I built a round ported box with 4" pvc but it kinda whistles a bit so as soon as I get another sheet of mdf, I have a slot port box designed and ready to build. If you go round port, make sure you have enough port area. |
