Posted May 10, 201312 yr Total volume = 5.333 (1 inch MDF)Port Volume = 0.64Tune = 31hz Box dimensions Total Box = 38 x 18 x 18Port = 3 x 16 x 23 Is this a good design for a ported 15, or two ported 12s?If not, what needs to change?also, could the subs be mounted on the top? Would this effect quality or spl? Edited May 10, 201312 yr by Dangercdv
May 10, 201312 yr what subs??? Total volume = 5.333 (1 inch MDF)Port Volume = 0.64Tune = 31hz Box dimensions Total Box = 38 x 18 x 18Port = 3 x 16 x 23 Is this a good design for a ported 15, or two ported 12s?If not, what needs to change?also, could the subs be mounted on the top?

May 10, 201312 yr What subs, and your port isn't big enoughHow do you conclude that with out knowing what subs
May 10, 201312 yr What subs, and your port isn't big enoughHow do you conclude that with out knowing what subs spoke too soon you're right that really cant be determined until the subs being used known. Edited May 10, 201312 yr by DanP
May 10, 201312 yr Author Sa-12s, or gcon 12s.Or possibly an xcon 15. Which ever is louder.This would be in the back of an SUV. Would the subs being on top be better?I could raise the height of the box and extend the port to what ever I need. Edited May 10, 201312 yr by Dangercdv
May 10, 201312 yr lol... 2 12's will be louder on the same amp. but i would suggest putting a little more thought into your build instead of what ever is louder. you can have subs sound good and be loud at the same time
May 10, 201312 yr Author Well yeah, of course I want it to sound good. I just want to be able to crank it up and get some good bass. Not competition or anything like that, but just some nice loud bass when I want it.I just want to know if this box is good to use? Edited May 10, 201312 yr by Dangercdv
May 11, 201312 yr we have to know what sub/s are going in to know for sure. pick your sub/s first and then work on the box
May 11, 201312 yr Sa-12s, or gcon 12s.Or possibly an xcon 15. Which ever is louder.This would be in the back of an SUV. Would the subs being on top be better?I could raise the height of the box and extend the port to what ever I need. design relates to product/subwoofers used .... you can get lucky or have decent output/sound quality using a random design for any sub but I wouldn't spend $300+ on anything and just go random on setup... but that's just me
May 11, 201312 yr Not sure what suv you have but how about 2 15 gcons? That would be way louder and sound just as good.
May 11, 201312 yr Author The 2 15 inch gcons sounds good. Won't I need a bigger box tho? As for the subs... I understand I need to pick, bit for this box, would sa12s or gcons sound better?
May 11, 201312 yr Well of course the box needs to be bigger. What's your max dimensions you can/want to use. For that box you came up with, I wouldn't put either of the pairs in that box. Your going to need a bigger port. How much, I don't know. I would have to get the specs of the subs. I'm not really sure if you would hear much of a difference between the subs. Both are proven to be some badass subs.
May 12, 201312 yr Author Okay, so if both SA12 and Gcon 12s are both bad ass subs, il probably stick with sundown then. So 2 SA12s, in that ported box. I will make another model of it tonight.How big of a port are we talking? I will also change the box dimensions to keep around 3-4 cubes of air because sundown recommends SA-12s get 1.5-2 cubes each.

May 12, 201312 yr Author This is another design of the same box. SAME outside dimensions. Total volume = 5.333 (1 inch MDF)Port Volume = 1.37037Tune = 31.5 hz I made the port 4 inches in width and raised the length to where I had it tuned around 31.5 - 31.6 hz. Its now 4 x 16 x 37
May 12, 201312 yr You can't make a box without knowing the amount of port area you need. You can't just keep making sketchups and ask if they're good. Ill check and see how much port area it should have. How much power are you puttin to the sa12s?
May 12, 201312 yr Author okay, so im pretty bad at calculating that. I only know how to tell how many cubic feet I have. So can I convert that?How close was I on my last design? (Last post on first page)
May 12, 201312 yr You should download the torres box calc. Type in google "torres box calc" and it's on the s m d forum. It's a very helpful tool. This way you can do it yourself and it'd be easier for you just to do it instead of asking and having to wait.
May 12, 201312 yr Author I had that once, didn't fully understand it. I'm afraid I won't know everything I'm looking at. Can I just get a conversion of 85 in2 to cubic feet?That will be my last question, with that I can build my box.
May 12, 201312 yr Are you trying to find the port area per foot?If you want to download it again, I can help you understand it. Edited May 12, 201312 yr by Bassink
May 12, 201312 yr Author well you said to use 80-90 in2 of port... i just want to know how many cubic feet that is. because right now my original design has .64 cubic feet, and the newer one i designed today uses 1.48 cubic feet.. I dont know how those numbers compare.I am about to leave the house, I will download it later tho and try to learn
May 12, 201312 yr It's just how much the port takes up. When you download the calc it will tell you everything you need to know
May 12, 201312 yr Author I know what it means... I'm trying to find how much mine takes up now. 1.5 cubic feet = ??? In2
