port length

[capple]

Now that I have finished cutting my 4 ports for my subs I think of this question. When the specs say the port is to be 10.27

[1louds-10]

the measurement is for the port itself. Also keep in mind that you want the port at least 4inches from the bottom or sides of the box. A good rule of thumb is keep it a way from the box the same amount of inches as the port size.

Thanks for the info. I did know that A guy was to try and keep the port away from the sides but some time this is not posable. Mine had to be close to the bottom.

Why is this a bad thing? The bottom two ports the subs on the bottom are the same distance away from the bottom as the top two are from the top. How close? I could slide a few sheets of paper between them. Will this create allot of port noise? Maybe I should try to put a 45 deg. angle in the port to get the mouth of the port away from the bottom? Tell me what you think. And also how to get the correct length with a curved port.

yes it would indeed be a bad thing:

The rule i go by is if the port is 4" make sure there is 4" clearance
6" - 6" clearance and so forth!!

If you do not have the depth...use an elbow...not a 45degree...other wise then againg you will achieve port noise from the sharp angle

Isn't a 45 deg. PVC elbow the same thing. Maybe you though I was going to cut the pipe at a 45? Or are you thinking of somthing else?

I thought you meant that the end of the port was very close to a wall, not merely running along side it - which is far less critical.
