Box size for two Power HX2 12s

[Musto]

what should i do about getting a box built for theese? about 5ft3 tuned around 33? just gettin some ideas...

[Musto]

going for 100% SPL.

why so high? this is for listning not competition, i mean i can expect 145 from this setup easy dont ya think.... look at my sig, all i gotta finish is the box and im set ;-)

i listen to alot of rap and anything with alot of bass, so i want the low notes to be loud, not high notes that ill only hear on a sound sweep. if im wrong let me know, but i think i need it ported around 33ish for that, right?

Ummm, that's not 100% SPL (100% SPL = Get this thing to hit the highest dB possible, competition style box ).

So you basically want a daily driver box ... ? In that case, I would probably tune it a little lower like 25-30 Hz and as large as you can It should provide a good medium between SPL and SQ and it won't allow your sub to bottom out on the low, low notes of Midwest and Dirty South hip-hop

lol.... thanks.

do you have like winisd, basboxpro, somethin like that? can you throw a 5ft3box ported at 33 and 2400 watts and see what happens? i think it should be around 145, i have a 95 thunderbird....?....( if i seem ignorant please excuse me )

126db? haha..... no way, my buddy has 1 1200.1 and 2 PUNCHhx2s hittin a 140... 126 is way off..... haha

sorry, once again i show my ignorance

this is the part of car audio i dont get... my friend hit a 141 on the dash with 2 punch hx2s and one 1200.1

its showin me hittin 143ish with twice the power and hella better subs, is the 2dbs worth it? its crazy to me how all this works, i guess you just dont know till you install it. thanks for the help man, you've helped alot- thank you

I just realized that linearteam.org has a free version of winisd pro. I know its a test but it has way more features than the regular free version I was using. I just plugged in my XXX 12 into it. I like the results. 8ft^3 tuned to 51hz shows me peaking at 130.322db's at 51.96hz. This is on 1580 watts that the RE amp I'm getting is supposed to put out. **** I sure hope my dad lets me cut out the bed in my pickup truck. This is gonna be one hell of a loud 12! I also checked going with a bigger box(10ft^3) but it didn't make enough difference to bother with a bigger box. I'm about to go play with it now and see what it would do with a lil more power....:p
