I'm building a ported box for my 12inch sub useing http://www.carstereo.com/help/Articles.cfm?id=17
for the box and

for the slot port.

I have seen some boxes with slot ports that bend at a right angle, I may have to do this.
Is it any different to calculate the length because of the angle? or just make the angle to length as if it were straight?

Also, the box is to be put behind the back seat. I was planning on making the port go from the back of the box to the front of the box which would be facing the back of the car.
The back seat is of course, angled back a bit. would that make it to much of an angle?

The angle is this, imagine a right angle triangle. One of the square edges is 152mm, the other is 364mm.

Thanks for your replys.... [yes]
