Odd port question...

[Fast1one 10+ year member]

Not sure how to attack this one...long story short im doing a hack job on my box to raise the tuning from 28HZ to around 33-34...I wanna hack a section of the port inside but I also need to hack off part of the front face of the port. I am only going to hack off one side for ease...how would I measure the port length when one side of the port is longer than the other? Heres a pic with the two possible answers...

Anyone have my answer? Maybe im overthinking this lol...

What are the dimensions of your port?

4 by 11.5...I dont see how that is revelant to the question though....I thought the picture would suffice...

So, the board you are going to hack is the only port board? The rest are also sides of the box?

Basically the right edge is the inner part of the port...the outer is the left edge... So yes only the port...
Edit: Got an answer...thanks for the quick one saywhat?

still measure down the center to the end of the port baord. the other side doesn't matter, as far as it's length goes, it would still be there if the port wasn't at all.

You could just hack it off in small increments until you get your desired sound.

the first pic there is the correct way of measuring it anyway.

Is that the "add 1/2 height to the physical length" method?

if its a slot port, with one edge against a wall of the box, then thats what you do, but this guy is wanting to make one side of the port longer than the other, with no wall as part of the port, so, the most correct way of measuring it would be the first way he drew.

Crap now im getting two answers...So basically to remove 5 inches of effective port length I will need to remove 10 inches from the left wall?

Lol no I wont...theres really no way of ruining it...unless you really are a dumbass...Why spend more time when it will take 5 mins to modify this one? Its a simple question, and if I get it wrong it wont change the tuning by a ton, around 2 HZ, just wanna know for sure, kay?
