You can with you cuurent configuration by adding more bracing. But since you haven't built it yet. Why not just make it a little smaller from the get go. 30 x 14 x 14 internal will get you really close. Might want to go 31 x 14 x 15 internal so there is a little room for bracing //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

with the 31x14x15 internal and the divider and the bracing, it's 1.62^3 each.

or are you saying increase the bracing?

Yes, you could increse the bracing you use. Or you could just shrink the dimensions and reacalculate until you get the size that you are shooting for. Either one will work, but like said above it would be easier to just make the box smaller since you have not built it yet.

thank you. i'll probly have a box plan for each set of subs made up here in a few minutes. thank you guys so much. you're wonderful.

No problem, just post it up. Sorry I missed some of your questions, I was gone for a while but it looks like you got all the answers you needed. I am in and out today. Trying to clean up my yard.

Good luck with your plans. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

ok, so the plan for the 12" rl-ps sealed will be 31.5 x 16.5 x 15.5 externally. 1 inch shorter than my max dimensions i posted. this is all including the divider/bracing/displacement. it comes out to 1.52^3 each. maybe use some polyfill to take off that .02^3

give me a few to work on the box for the 12" brahmas.

Are you sure that you posted the dimensions correct. That will come out to like 2.3 per sub before displacement and bracing. That is alot of bracing.

Are you planning on using that Tantrum on the RL-P's?

Nevermind, stupid question. I was reading the specs wrong. Looks like you will be giving each about 700 watts. That will sound pretty good in 1.4-1.5. So you are perfect. Just check those dimensions you put down they dont sound good.

 

[dkguitarist 5,000+ posts]

the dimensions i remeasured. it is all correct. 1 inch off the length. bracing will be 7" x 7.5" x 3/4"

 

[amr952 10+ year member]

I just cant read today lol. It says externally. That will be perfect, as long as your bracing brings it down to 1.52.

Sorry about that. //content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif

i didn't have it written down cuz it was 1.62 each. so i just knocked 1 inch off the length and use the same calculations for everything else and it came out to 1.52. did it twice to make sure.

 

[dkguitarist 5,000+ posts]

as for the brahmas, using the same calculations, i came up with 1.61 each using the 31x15x14. i think i need to change something.

Something is still not right, It looks like after bracing it will be about 1.62

31.5 * 16.5 * 15.5

subtract 1.5

30 * 15 * 14 = 6300 / 1728 = 3.64 total

3.64 / 2 = 1.82

After sub displacement

1.82 - .18 = 1.64

After Bracing

7 * 7.5 * .75 = 39.38 / 1728 = .03

1.64 - .03 = 1.61

Did I miss something along the lines?
