View Full Version : Box design help
07-19-2011, 05:10 AM
Hey this is a pretty bad sketch but it wash in paint so forgive me..
I will try to explain it some first
far left is an outside wall
the next wall is the end of the enclosure.. it will have two 3" aeros firing into a loading wall that is 5"s away which is the next wall
now then is that an appropriate loading wall? should I square off the loading wall or can I keep the the same triangle shape as the rest of the box? I plan on tuning at 35hz as I was told the loading wall can help me still hit the lower frequencies.. Is this a good plan bad design? its the first box I have ever designed at all so help would be great..

aeros big enough? I was thinking maybe some 4"? I don't think 6"s would fit.. as the are like 8+ after flare..
Do 4's. You want to hit me up? I can check to make sure disp. are right.

alright will do 4s.. other than that is the design fine.. what displacement you talking about? sub, port?

anyone? I know someone online has made some boxes before.. cmon..
Well, all of them. Box size, sub and port displacements. Just double checking your work if you want me to.

square is 3x20x43 = 1.49
triangle 9x20x43/2= 2.24
3/4" wood disp
-.37 back wall
-.41 front wall
-.08 both side wall triangles
-.05 both side wall squares
2.54 after displacement of the wood.. correct me if I am wrong..
side triangles 20x9 x2
side squares 3x20 x2
can't find subs but if I did
5.25 mounting depth x area of magnet diameter(6.25)x 4 of em
I get .37 for all 4..
so thats 2.17 after displacement before ports...
thats approximately the box.. 1/2 I understand is probably not ideal.. but I am thinking do that and run some all thread for bracing..
Whoa this box is a different size than I thought it was.

25"H x 43L x 12bw x 2tw
square 25x2x43 1.24
triangle 25x10x43 3.11
total before disp 4.35

Drawing of new dimensions.. the max distance is edge of sub to outside wall.. distance to port opening will be smaller obviously.. is this enough room?
The question on the bottom is, somewhere between the subs and the ports should I put something or is it fine just shooting right into the port?
and those are 4" aeros now sorry

Really long/skinny box can act like a line.. I would speak the subs out from the picture, not that you could mount them that way due to depth anyway.
I just skimmed over but its obviously a truck box? Fire into the passenger side a few inches away and youre good to go.

1. yes its a truck box
2. speak the subs out from the picture??
3. I have always heard fire into drivers side?
