so i finally figured it out

H=19inches
W=13 inches
D=20 inches
1 inch MDF
Divided by 1728 gives me
1.948 cubic ft
my sub needs 1.95,
this small variance wont harm it will it ?
port is 4inch x 11.25 inch
should be 35hz tuned

Please correct me if iam wrong.

 

You need to account for the subs actual displacement as well as subtract the volume of the port to know the usable internal air space.

 

ugggggg i did not even think of that, can you give me some help?

my specs tell me this from the audiobahn site
Air Space (Cu.Ft.) 1.95
Port Size(inches) 4 x 11.25
Port Vel. (%) 13.33
-3dB (Hz) 12.06
Tune Freq. (Hz) 35
Sub Disp (Cu.Ft.) 0.4
Port Disp (Cu.Ft>) 0.093
Total Vol (Cu.Ft.) 2.5

With those specs, can someone give me the dimensions i would need to build the perfect box for this sub?
Extreme Thanks in advance.

Or give me something that can make it even better
here is the link for my specific sub
http://www.audiobahn.com/Audiobahn06...ortal_subs.pdf
its the middle model wich i included up top , awes12

 

:P:P

 

whats your maximum dimensions?

 

err seems 2.5 cub ft total volume

 

So i got all these programs i tried for speaker box creation, man i cant figure these out.

 

whats your max space to work with? maybe i can come up with some dimensions for you when i'm bored.

 

Basicly the entire trunk

 

what subs? quantity? desired tuning freq?

 

1 Audiobahn AWES12P , 35 Hz

Thanks for the design. Looks huge but i can make it work i guess.

Do you suggest any Poly Fill ?

 

not my design, but a buddy of mine. i was going to draw one up, but remembered he had a few of his uploaded.

it's not entirely that big. it should fit without any issues. i can fit a 36" wide box in mine.

no need for polyfill.

 

The ported box for my JLAudio 12W7 only has roughly 2cuF, and its tuned to 36hz.. according to WinISD, the box does 120db @ 50hz.. is that good? lol

 

no program can give you real numbers like an actual spl meter...

 

Where can i get my hands on one of those?

 

they're quite expensive. best bet is to ask various audio shops to see if they have a meter for you to use (for a fee of course).

iirc the TermLab mic is $500+

 

Never mind. lol

 

So i have yet to find time to build this box, can some one suggest a builder that can ship and a decent price ?

 

www.soundsolutionsaudio.com

has 2 builders on that site, that are pretty much professional

go to the Manufacturer Forums and look at
fisher customs(bjfish11) and pound that sound(Thumpper)
they should have decent prices and will do a damn good job!

 

So i havent yet got to making this box, i have 2 options now, i can build this box or buy a new sub set up, 2 DLS subs in a premade box just for them, What would you do ?
He said there $599 for the entire setup but there on sale and if i take them this week he will give me them for $350, is it worth it ? I think there the W612 Models
