Can someone please make me box plans?

[THXdts 10+ year member]

Yes, it's usually not nice to ask for free, but what can I say. I don't know how to do box plans. If anyone has any spare time in there day, and feel like doing this, it would be awesome. I am looking for 1.5 cu ft net tuned to 34 Hz with 20 sq. in. of vent area. It is what Sound Splinter sugguests for the 12" RL-p. Thanks alot. If possible at all, I would like it to me more square..not like 29x13x13. That just seems akward as a box shape to me. Unless it takes away from the performance, then just do whatever.

here's a squarish box:

http://www.subwoofertools.com/forum/ported-box.asp?Ew=19&Eh=19&Dia=6&Xmax=12&Vd=.1&NumW=1&Vb=1.5&Fb=34&Qts=&Vas=&Fs=&CE=0

look at all those port walls //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif and due to all those 180 degree turns the ports have to be wider, and therefore longer, making the gross box volume large (4.18 ft^3).

if you go with a less square design it'll be much easier:

easier to make, port area more normal, shorter port, gross box volume

what vehicle is it going in? i'd just start with something as wide as the space you have, and a desirable height, and let the math figure out your depth. i don't really see any advantage in going with a cube.

There's a sticky at the top of the forum..

That's cool but the only reason I don't like that one is that it gives me like 10 port walls. I only want like one..

here's a more square design with only two port walls (similar to the one mobeious did in sketch up):

http://www.subwoofertools.com/forum/ported-box.asp?Ew=18&Eh=14&Dia=6&Xmax=12&Vd=.1&NumW=1&Vb=1.5&Fb=34&Qts=&Vas=&Fs=&CE=0

i like that site because it gives you a full cut sheet, so everything is real easy //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

You don't want a cube no matter what. I believe it's the second worst shape possible for a speaker enclosure unless you round off every single edge. Rectangular prisms are used for a reason; they have medium performance with the most simplicity.

So this one posted is probably the best? And thanks xluben, thanks. That site is indeed cool, but the only flaw is that whenever you put in dimensions it always gives you a shit load of port walls.

Yep looks like it, but it's free, and you get what you pay for.

 

[xluben 10+ year member]

it doesn't have to be that long and thin, you could do something more like this:

http://www.subwoofertools.com/forum/ported-box.asp?Ew=24&Eh=14&Dia=6&Xmax=12&Vd=.1&NumW=1&Vb=1.5&Fb=34&Qts=&Vas=&Fs=&CE=0

i wanted to know the max width and height you have in your vehicle and then i could come up with something that would fit nicely.

That one looks ****ing perfect. The only problem that I see is that you are using 12mm for the xmax and displacement at .1 cu ft //content.invisioncic.com/y282845/emoticons/uhoh.gif.c07307dd22ee7e63e22fc8e9c614d1fd.gif.

Eh?

fixed the driver displacement. the site just uses xmax to determine port area, you can change it to get whatever port area you need.
