Brad Smith Posted September 1, 2012 Report Share Posted September 1, 2012 I've got a concept cex-12" if any one can tell me a good port size I'm building the box for this sub but and going too be using something way bigger that's why I'm over sizing the box. Thanks. Hope some one can help me out with this so I can start my build soon. B-) Link to comment Share on other sites More sharing options...

Brad Smith Posted September 1, 2012 Author Report Share Posted September 1, 2012 Going to being useing a better sub but for now was just going to use the concept sub for now I'm building the box too fit in the truck of my bmw318-is. And right now it's in a junk ass bandbass box that bows like a Bitch just trash box I'm going 1" and want to use 2.0-2-5 cubic feet box don't know really much about ports and sizeing them the size I want to use is 25"X12"x14" but I've got room to go up too 30"x15"x15.5" max and I know that way big for one 12" or maybe run a 15" I'd like to get in the 140db or so any info would help thanks Link to comment Share on other sites More sharing options...
Jessica Posted September 1, 2012 Report Share Posted September 1, 2012 Well, after port and sub displacement with your dimensions you are too small for a 15, but really close for a 12" Unless you want to go with round ports outside the box. And to do 140's with one sub, you will need a beefy sub. so that is more displacement and less air space yet. I would say, in my opinion and thats what it is, is get a serious 12" and build a box to it's specs. Most people here recommend tuning in the 30's for daily. If you just want an spl monster then you will have to do some work to see what your car's resonate freq is (car's peak) and tune near it. There are about a thousand people here that can design a box for you, some good some bad. Just get second opinions on whatever you decide to go with.

412 CVX Posted September 1, 2012 Report Share Posted September 1, 2012 I can't find any specs on the woofer. Just say no to Ground Pounder Customs. My temp system build log More box buildssome cars do over 170db with one sub, so clearly my two 12"s can do that in my car, with my knowledge too! look out bitches! I'm with captain stupid.
