alright i just got the max dimensions for the box.
W=32 in
H=16 in
D=16 in
this is the max i would like to go a little smaller if possible :P
remember its for 2 subs not just 1 .

what do the specs for the sub say each sub wants for volume? ...multiply that by two and add 2x speaker displacment, and theres the total volume you want!

they only have the specs for dual 4 ohm not dual 2 ohm. gay. or is there no difference in box size between dual 4 and dual 2?

another Q for ya.
http://www.edesignaudio.com/ep/kboxrec.htm
the site gives u 3 different box size recommendations.
whats the difference between small box, daily driver, and audiophile?

small box is the recommende smallest u can build....daily driver is for the everyday person (not for competitions) and audiophile is for those who want extreme SQ.

what type of SQ/SPL mix are u looking for?

do u have a preference on ported or sealed. Sealed is the best for SQ, but ported can sound great too and be louder than sealed. Ur building the box urself, right? If u r then i suggest a small sealed for the
better SQ. what are the max dimensions u have to work with?

ya im going to try to build it myself. :) i impressed my dad when i told him that iwas goingto build it myself. anyways i will definitely go w/ sealed since its the eziest to build.
max dimensions are.
W= 30 in
D= 12 in
H= 14 in

kind of odd terms....but what basicly the first two options are for someone who wants some bass, but doesn't want to loose all of their space...if you have the room i would go with the Audiophile type.....so if there are 10's you want 1.0 ft^3 + the 2x driver displacemnt.....probably design something around 1.25-1.5 cu ft if they are 10's.....1.75-2.25 cu ft for 12's.....sealed volume is not real exact....get it in the range the sub wants and your "generally" going to be ok....your only going to be tuning if you port, which i wouldn't recomend for the first enclosure.

alright so im going to go w/ the audiophile size box.
another Q popped into my head.bracing..... is just one piece of wood in between the two subs a good enough brace?maybe even double to make it 1 1/2 in thick?

i would recommend a box that has the cubes evo suggested, but separate chambers(so his recommended cubes for each chamber)....one for each sub. so then the "bracing" for the box could actually be the divider that separates the chambers. Only on piece, so 3/4" thick

ok i got these dimensions(exterior)
W=28
H=14
D=13
i calculated it out and got the internal volume to be 1.982 ft^3
can some1 calculate it and make sure i did it correct?
sub displacement=.08 ft^3 per sub
3/4 in MDF
3/4 in MDF brace(single piece divider)

{ [28-(0.75*3)] * [14-(0.75*2)]*[13-(0.75*2)] /12^3 } - 0.16 = 1.9821 ft^3....you got it!! :) good luck with that....personaly i think that center divider is plenty big for the bracing.....i dont know what other people think, but when i started building boxes i made a box for each sub and glued and screws them together....you get a little more solid of a box this way....but i think most poeple would generally think its overkill :)

yeah, i think the divider is enough for bracing...that's what i used on 2 of my boxes and they don't flex at all, no problems.
