Going to do a vented enclosure and got the demensions for a vented box from JL. My question is, I want to change the demensions of the box (keeping the same cu.ft.) but then I would have to change the lengths of the slot port pieces (again keeping the same overall length width and height of the slot port). Hope that makes sense, is this ok to do or will it change the tuning? |

Thanks again |

Silver Member Username: Simple_smithLapeer, Michigan United States Post Number: 118 Registered: Dec-08 | Personally, i would do a downfired ported enclosure since you have a good amount of room with the extended cab. So i kinda have a similar question. I'm making a center console box for my 92 sonoma standard cab and i am planning for the port to be along the back of the cab, but its gunna have to be a triangle port. Are there any different ways to figure this than finding the port area of the triangle port, then using and equivilant rectangle port to find the correct port length? |
