good luck getting any help we dont own the ''right'' subs for here. lol
you could always use the calc. on this website
http://www.subwoofertools.com/forum/ported-box.asp. its pretty decent. it will give a cutsheet and all. i have 3.25 cubes at 35 and i like it. for that calc just incase you don't know your xmaxx is 14.1 and your sub displacement is .08 (assuming you have the 06 and up model) and for a box that big i would suggest some type of bracing. if you have any questons on bracing just search the forums theres tons of stuff on that. actually theres alot of stuff on the l7 to.

you don't have to make the box 3.25cuft. for it to get loud. matter of fact, I'd say stick to around 2 cu.ft. tuned to 33Hz. the subwoofertools.com calculator is great, I use it for almost all my slot port boxes. So you have size and tuning, now go to that site with the xmax (found in the manual) and you're all set to use their program. It'll tell you every panel

the sub displacement is .08 or .8? I have an 06S12L7 4ohm

2.5ish cubes for daily, imo. 3+ cubes is big for a 12.
Box size depends on the driver, not the cone diameter.

^ are you doing S1 this coming season???
anyways, sub displacement isn't 0.8cu.ft. I don't think its 0.08 either, more like 0.12cu.ft.

Yes. I decided that I didn't feel like putting up with the gay AS1 rules and would rather do S1. I don't have the time to constantly switch stuff out (like batteries) to do AS1. Are you doing Meca?

Shoot me a pm man. It would be awesome if you wanted to meet up before the show. I could let you practice on my TL if you don't have one.

so... i built my box today. i will post pics when I can upload them (56k).
external dimensions: width-36 Height-16.25 depth-16.5
internal dimensions: width-34.5 Height-14.75 depth-15
i had home depot make one long cut in the MDF, but I realized that I made them do the wrong length cut, so I just followed my same plans and instead of shaving 1.5" off the smooth bench saw home depot cut I made the box a little bigger. i believe it is:
Cu Ft: 4.0 (Excluding port)
Hz: 32
I used this to figure out the tuning. Port: 2.75 X 14.75 and length 18.75
I used the entire box volume (4.4 cu ft) for the calculator, is this correct?
