    ...why didn't you measure your own trunk...

    To be honest, I really don't know, I think I was wasted and he was sober and so on..

    height=15

    width=33

    depth=21

    port dimensions

    height=13.5

    width= 4

    length= 29

    sub and port both facing the trunk with the port on the drivers side

    comes to a net volume of right at 3 cubes with a tuning of 35-36 hz...if someone wants to draw that up be my guess cant do it on this computer

    Thanks man, sorry for the inconvenience, sh*t got messed up. Haha.

    Umm, i can draw that up for you pretty quickly tonight after i get back from school.  I drew up one for my lancer yesterday, 15" Fi BL, 3.48cuft @32Hz 54 1/4 sq in of port area.

    That would be great man. Do you know if those dimensions are correct for 2 12" Alpine Type R's running a total of 1200 wrms up. Dual 4 Ohms.

    You don't know how much I appreciate it.

    what subs and amp do you have and what are the max dimensions the measurements you have are around 6cutf @25hz
    That's pretty much the max measurements. 2 12'' Alpine Type R's with a 1200wrms amp.
    are they meant to be internal or external dimensions? what thickness wood if external?
    They are meant to be external dimensions. The thickness is 0.75 in.
    So much missing information here...I'm assuming they're 15s...
    I wish, they are 12's.

    I am just going by what the guy on here told me. So i'm sorry for any missing information.

    So a fellow member of the forums gave me this. And I was wonder what everyone's critique on it is. And I still don't understand the L port part of it. So any help is much appreciated.

    Dimensions:

    Height-27 width-30 depth-18

    Port: height-15.5 width-3 depth-24

    3 cubes net with 15.25 sq. in. of port per cube and a tuning of 36Hz.

    I would really like to see a 3D model of this. That would make it a lot easier, if anyone could take the time.

    Still really need help with the L port.

    Thanks for everyone's help in advance.

    Bryan.

  22. Torres' Box Tuning Calc and Google Sketchup HELP!

    First thing you need to know is the recommended air space needed for the sub your using.

    Next thing you'll need to know is how much space is available to use in the trunk so you don't choke them with too little trunk space left.

    Once you know those you can then decide on the size and number of subs you want to use.

    To use the calculator after knowing what subs and space you have just plug in the H/W/L to get an idea on what your gross F3 is and will fit in the space you have.

    Once you have the size of the enclosure figured out now comes the part of tuning it, you can calculate slot ports or round ports depending on how you use the boxes, the first row is for slot ports and the bottom row are for round ports and the length will determine actual tuning.

    Most people will use the general guide of 12" to 16" of port area per cf or more of air space of the enclosure for slot ports, round ports can be anywhere from 9" to 12" per cf or more and lastly aero ports can be as low as 7" to 12" per cf or more, some sub will like more port area than others so sometimes you'll need to experiment.

    The misc. section allows you to enter sub displacements, # of common port walls and other items to help with getting as close to an accurate tuning as possible.

    Once you enter everything into the calculator you want to make sure your NET F3 (Net Volume) is in range of the recommended enclosure size so you may have to play with actual box size and port lengths to come to the desired tuning your looking for.

    Might be some things i'm missing but it is early and not quite awake yet but this should help you along in using it.

    Jeez dude. You are a life savior. Very informative for not being awake. Thank you very much.
