Is bigger better?

[Duran 387]

Thank god. Someone said aim for 20inches of port area per foot earlier, so I'm sitting here for like an hour trying to design a box that would meet all of my requirements and i couldn't get it to add up right. lol

I think I'm going shoot for 8-9 cubes at 34 hz

Given the displacement capabilities of the SX, I recommend a total of 115 square inches of port area minimum, if you want to tune at 34 Hz.

Notice, internal area isn't mentioned, because it isn't needed when figuring port area, it is only needed when determining efficiency, maximum power, and tuning of the enclosure.

WOW what program did you use to build this? I am trying to find a good program to design a box, and this is like perfect for what I was looking for so that when I design it I can see how it will turn out! but I cant find anything good online...

Google Sketchup

oh lol so simple.. im an idiot .. I saw that on google search when I searched for a program and ignored it assuming it wasnt what I wanted and the whole time it was..

Lol, yeah it's a nice program once you figure it out

[kamahaobuilt13 1]

I would go with the 2nd choice if the port was at the wall. & I would prefer the box be tuned to 30hz

Well it won't be happening anymore.

Mines the Expedition. Head on going 40.

lol well that's unfortunate

[orlando144 20]

That sucks man. I was looking foward to seeing this box built, i was building one similar.

Still working on her! Got the engine all fixed up, just need to put my car on a frame straightening machine. (If that's what they even call them) Frame is a little bent in the front, and it caused everything to shift over a little bit...Straighten the frame, get a new front end and fender...throw some paint on, and she'll be good as new. Once it's all finished you can expect to see me finish building the box.

there car is massss more f'd than urs haha. i have a '95 ranger on 35's so its a fairly big one and i rear ended a kia doing 35. my truck dont look any different after one night of fixing the grille and bumber after the accident. her kia was totaled. thats the BIG difference in american cars, and imported cars.

They crumble to absorb the energy of the collision, totaled cars are better than totalled people.

Right you are, Ken

[Alan Palmer 3]

crumbles ftw.

although i remember my toyota pick up.. thing was a block of steel. i would back in to the concrete poles at circuit city as a park assist. i took chunks out.. bumper never even had a scratch. had to roll it to do damage..

anyways, get it straight, and build this box! haha.

second one.
