cuz i h ave the design for the one with aeroports but i wanted to make sure it would be alright for my setup. i dont wanna build this box and find out its not what i wanted, you know? but i guess ill have to do the trial and error to find out...

biggest difference is usually the thickness though.

i have thin walled 6" PVC pipes, same wall thickness as PSP 6" pipes. then I have some regular PVC pipes, which are thicker.

& if you're looking for any 6" pipes, they're for sale.

i was just gonna pick some thin walled 3'' along with the mdf if they have it.

another thing i didnt understand is Fi said the bl's need 12-16 sq in of port area per cu. ft.

so i have 2.8 cubes on my design, so that would make the port area 33.6 going off of the 12 sq in of port area fi reccommended. but the 2 aeroports on the design are 3'' wide, and 9 13/16'' long, wouldnt that give me way more port area then 33.6 sq in?

2 3" ports have only 14 SQ in. of port area total. i would do 1 4" port and a smaller box.

Not at all.

Square Port Area= H x W

Round Port Area= Pi x r^2

So, 1.5 x 1.5 x 3.14 = 7.065 x 2 = 14.13

You need more port area

One 4" = 12.56sq in

For the port area you need for that box I would do a single 6in port. Or two 4" aeros.

well i seen an earlier post and re's website has a box calculator, which i didnt know about.

i entered in my dimensions, everything seems right, i have 30 sq inches of port area (if i make it any bigger my port wall has to be really long to reach my desired tuning frequency of 32hz and takes away volume, so i kept it minimal) i have 2.212 cu ft of volume with all displacements, and kept within my max trunk dimensions. has anyone used this calculator and is it accurate? im sorry for all these **** questions but i really wanna learn how all this works!

two 3" ID pvc pipes nets you a port area of 14.13 square inches.

id do one six inch aero if you're dead set on aeros, slot port would e the ideal way to go.

Can you post the specs for your sub?

They will look like this

Fs: 28.4 Hz

Re: 0.7 Ohms/coil

Qms: 05.39

Qes: .49

Qts: .45

Mms: 211g

Cms: 0.15mm/N

Sd: 481cm^2

Vas: 48.3 l

Spl: 85.4dB 1W/1m

Bl: 10.4 N/A

Xmax: 27mm

then give me the maximum outside dimension that you can fit for your box and ill throw somethng together for you

32x15.75xx11.75 is as big as you can go?

or is the H 15" including a invisible board?
