dcofer Posted July 21, 2011 Report Share Posted July 21, 2011 (edited) I am building a box for my buddies civic si and he has two(2) Hifonics HFX12D2 subwoofers (economy set up). the box is going to be sealed from the trunk firing into the cabin. What do you guys think of these calculations for the box?It is going to be a standard L port with both subs in a common chamber. Here is a screenshot of the program: The 12 sqin. per 1 cuft. seems low but if it will still be okay then that's all that matters. Do these seem like good calcs?

kam311 Posted July 21, 2011 Report Share Posted July 21, 2011 I'd say 12 is alright man, some people like more, some people like less, I think ot really comes down to just trying things out.

Craig28 Posted July 21, 2011 Report Share Posted July 21, 2011 thats fine. for slot ports you usually want 12-16 sq in per cube Quote TEAM DC Everything is a 150 on th earometer Well I guess punching a woman is a good way to test your strength! You never know how strong you are until you cold-cock a woman in the head and break that bitches jaw. Next time she tries to punch you in the stomach, whip your wiener out and chase her around.

I'm used to building for my jeep so this build style is a first for me. I will try and get a model up later today. Quote Link to comment Share on other sites More sharing options...
dcofer Posted July 21, 2011 Author Report Share Posted July 21, 2011 ok here is the model I made a little bit ago, its fairly simple design but hopefully effective. Let me know what you think of it. Hopefully the pictures aren't too big. Quote Link to comment Share on other sites More sharing options...
BJD3 Posted July 21, 2011 Report Share Posted July 21, 2011 (edited) You have three common port walls, you didn't take out the displacement of the subs or bracing. How are you going to get a height of 13.75? Edited July 21, 2011 by BJD3 Quote Anti Peel and Seal...lol You may be offended by the above.

How are you going to get a height of 13.75? I haven't really used that calculator much so ill have to tweak it a bit, i might have taken a pic of the wrong dimensions in the calc, the model is build right I will go and fix the program though, thanks for pointing that out for me. the bracing was an after thought I will add that in right away. Just so I can learn a little more what constitutes as a common port wall? I could probably guess but would rather get the right info. Again thanks for the criticism tis how I learn.

dcofer Posted July 21, 2011 Author Report Share Posted July 21, 2011 (edited) Ah ok I remember reading that stuff when I downloaded the program, just must have forgotten, thanks. Here is the updated program screenshot. I'm only using 0.5" dowels as bracing hopefully that should keep the box stiff in those weaker points of the box and I assumed the bracing displacement was in ft^3 so the displacement was quite small but I added it anyways. I also there was no info on the woofer displacement even in the manual so I just assumed 0.1 ft^3 (if this is bad or way off let me know). I also fixed the port length since I noticed it was off from my model. Thank for being helpful and not just reaming me for not quite knowing hoe to use the program fully haha.

RAM_Designs Posted July 21, 2011 Report Share Posted July 21, 2011 1/2" dowels will split really easily. I suggest going no smaller than 1" in this case, and be sure to pre-drill.
