ZCON 12D2 in 3 cubes @31Hz Enclosure, port question

[kj4jaq 5]

Vehicle : 2010 Toyota Tundra DC
Location in the vehicle: back passenger side
Box size: W:22, H:19, D:17, using 3/4" = 3.0 cubes
Subwoofer make and model: SSA ZCON 12 D2
Subwoofer Size: 12"
Number of Subwoofers: 1
Type of Port: Aero Preferably (have a flared 3" aero already in my possession)
What type of music do you like?: DNB
Everyday listening
Tuning Freq (Hz): 31hz
Volume : 3.0

-------------------------------

So my question, is the 3" aeroport going to be large enough diameter for this sub?  I've read where people have used ports that were too small for the sub utilized, and didn't want to run into the same issue.  Any further suggestions or ideas for box and/or port(s) is welcome.  If you have further questions for me in regards to this, feel free to ask as well.

One 3" aeroport does not have enough area.

 

What amp / power will you be using?

[kj4jaq 5]

RF 1500BDCP, and since it isn't enough area, i guess it will have to be a square port then

You can play around with port area here: http://bitpusher.in/?p=portgraph&driver=3&xdrivers=1&rms=1500&tuning=31#bottom

messing around and researching, i see where it says square port HxW ratio shouldnt be more than 1:8, what is the reasoning behind that? 

[pmureika 31]

Those zcons like big boxes.

[kj4jaq 5]

understood about the big boxes, hence i wasnt going minimum volume requirement chose a happy medium at 3 cubes

That's what I was running mine at. Some people on the forum suggested bigger.

[kj4jaq 5]

i cannot go any larger then the box dimensions given in the first post..that is the largest i can go without taking seats out, and i am not willing to do that

[S.DeYoung 968]

If you have more room, go even bigger on lower power

[pmureika 31]

Thats what I wanted to say.

What you suggested is 3.0 before port. Going to be a small box for the zcon

[kj4jaq 5]

i could go up with height some, and possibly depth, but width is restricted to 22.5..unless i had a non-rectangular box, then that would add 13 x 6 box to the bottom

[kj4jaq 5]

let me go back to the drawing board with this... thanks for everyones input.  it is much appreciated

The above link shows no port height to width ratio, its port area vs port speed.

eric is the 13x6 the area between the seat brackets?  Is that centered in the 22.5 you have for width?  I can start working something up, too...

 

Also- a depth top and depth bottom....a wedge will get you some needed volume.

 

Guys- would a sub forward/port up work well?  OR we could use the 13x6 area for port and extend it forward pointing under the pass seat...I have some ideas...

Whats your thoughts Bassink?

I used the port up in my jeep and liked it.

[kj4jaq 5]

yeah the 13x6 area is between the seat brackets, i have to get back to my truck to verify that it is centered in the 22.5, still stuck offshore..unsure when i will get back in

[Lee Carter 150]

I am thinking along these lines...haven't done the math- just a general sketch.

 

[Lee Carter 150]

I was in a hurry when I made the last post...to be clear, that is to the dimensions 22wx19hx17d with the port being 13wx5.25h(for a net of 11.5x4.5, 52ci of port, ~17ci per ft^3)  The math I didn't work out was the port length needed.  Just wanted to know if the theory of the external port was solid first.

i was also googling stuff up, in addition to your link you provided.

I was thinking he would've been in here too...

[kj4jaq 5]

Leedog, the seat rails are not spaced evenly side to side, from the left rail to the wall is 5.25", from the right rail to the wall is 3.25

[S.DeYoung 968]

So that port would be running under the seat?

Did I miss what kind of vehicle?
