friend is in need of a box.

So a friend of mine just got 2 sa 8 v2's and has yet to build a box for them. the last box we made for him (for his HDC3 15) was made with RE box calc and from everything ive learned that is not the way to go. and i have a Macbook so i cant get torres or anything like that.

Here is just some of the general info
2010 honda civic 4 door

box is in the trunk

2 sa 8 v2's

either a sae 1000D or scv 1500d for amp (he hasnt made up his mind yet)

max box dimensions are 32 deep 26 wide and 17 height.

here is the one major stipulation. For some reason he really wants a labyrinth port box (im assuming that means a multi folded slot port). for reasons im not really sure.

basically he said he wants as loud as two 8's can get and still have a musical range.

any ideas for something like this? he listens to alot of music that is mostly right around 35 to 45 hz range for the most part but then he likes to go low just to see the sub move basically.

i suggested to him around 35ish to 38ish hz for tuning but he just said he wants loud (dont think he fully understands the tuning thing, not that i FULLY understand it either but i have a little better concept of it)

the only thing i really dont understand is that he really wants this to be a "labyrinth" port box.

any help would be awesome. and sorry for the long post i just wanted to go ahead and knock out alot of the information.

Can those 8's handle a 35 hz box?

I'm not sure I understand the question. The volume of the box (along with port tuning to have cone control) is what "controls" the cone, right? Obviously along with power too. I mean you could have a 10 cuft box at 35 that the subs would have hardly any control In vs say a 1.5 cuft box at 35 that the subs could do nicely In. But I'm no box designer or specialist so honestly I know it goes into much more detail than that ( port area, length, shape, enclosure geometry, etc) but I couldn't tell you exactly how everything is effected. Mainly just basic stuff for me. That's why I need help. :-) thanks!

I don't know if 8's can dip that low. I asked that because if you didn't know, it would atleast be a question that would help you out along the way if it gets answered.

I gotcha. Thanks! Never thought about that. Neither of us have gotten to hear them in person before buying mostly due to lack of enthusiasts around here so we were going based off reviews and YouTube haha

SA-8s can handle a 35 hz tune just fine, in fact a 35 hz tune is exactly what Sundown recommends for them.

You could put them in a box tuned to 20 Hz if you wanted. They would just have a really funky frequency response that probably wouldn't sound great.

That's what I was thinking but I didn't want to say it without knowing for sure.

any designers out there willing to help us out? neither one of us have access to a windows based computer so we are pretty limited on design programs which kinda sucks. i would greatly appreciate the help! if anymore information not already given in the first post is needed i will gladly include it!

This is where that math you thought you'd never use comes in handy, you don't need a computer to design a box just good old math.

Any formulas you'll need for tuning and such are out there you just need to find them.

That being said a lot of people's definition of "music" is a clipped 30 hz sine wave with some 80 IQ knuckle head grunting about committing crimes and his genitals.
