gmoxley1 Posted December 18, 2014 Report Share Posted December 18, 2014 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 info2010 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.

gmoxley1 Posted December 19, 2014 Author Report Share Posted December 19, 2014 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! 1998 chevy blazer 4 door stock alt 105a Battery: Autocraft Gold 75-3 Big Three in Sky High Car Audio 4ga subs: rockford p2 12's (soon to be sundown SA 12's) Sundown SAZ-1200d on the subs Mids and Highs: Infinity kappa 6.5 mid in front doors and tweets in Dash sae 50.4 for mids and highs SMD OM-1 on the subs Link to comment Share on other sites More sharing options...
Ahmed Johnson Posted December 19, 2014 Report Share Posted December 19, 2014 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. Link to comment Share on other sites More sharing options...

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 1998 chevy blazer 4 door stock alt 105a Battery: Autocraft Gold 75-3 Big Three in Sky High Car Audio 4ga subs: rockford p2 12's (soon to be sundown SA 12's) Sundown SAZ-1200d on the subs Mids and Highs: Infinity kappa 6.5 mid in front doors and tweets in Dash sae 50.4 for mids and highs SMD OM-1 on the subs Link to comment Share on other sites More sharing options...
Triticum Agricolam Posted December 19, 2014 Report Share Posted December 19, 2014 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.

gmoxley1 Posted December 20, 2014 Author Report Share Posted December 20, 2014 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!

Broke_Audio_Addict Posted December 20, 2014 Report Share Posted December 20, 2014 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.
