I have never built a box and am trying to learn. I have all my dimensions that I need and I will be building a type 2 wedge box that is ported.

What I don't understand is how the "port" design works. and any sort of walls that I would need to put within the exterior walls.

Is there a guide that can help me with this or can some of you give me some tips?

hah.....ummm

for a ported box you have a port and there are walls within the box that "tune" the box. that is what I need help with.

a ported box is not a box with 4 sides and a whole in it. I wish it was that simple.

The port is a certain length depending on tuning, net volume, and port area. Someone link a ported box calculator for him. That should get you going.

Very good calc, it is accurate unlike many other ones out there. If you have any more questions let us know and we'll help you out the best you can....

Will probably be easier to use an "aero" port on a wedge 2 box. Last one I built I used a 4" aero out the angled face.

Use one of these calculators:

Precision ports are available from partsexpress....

what is an aero port?

and these calculators seem to be for standard cube boxes...if Mine is a wedge 2 box will that change things? I can give it basic measurements of my box but not exact.

Basically a tube. Less port noise because there are less corners and sharp angles.

even though your box isn't a cube, it still has a volume :) aeroports are simple, just put the numbers in the right boxes on the psp-inc calculator and it tells you the length. but when you use the volume, don't forget to take into account the displacement of the woofer
