4. ## Re: Help with slot port.

why are you set on that length? you should decide on a port area first, then calculate the port length

5. ## Re: Help with slot port.

Only set on 32hz that is the tength the calculator gave me

14.5x3 " port @ 32 hz is only a 10" long port

what walls ??? port walls?? Its 23 3/4 in long..... You make a bend 6.5 inches from the back wall of the box and then make the port the rest of the length along the back wall...

13. ## Re: Help with slot port.

your port will be 16inches down the depth side(24 in ) and 8 " down the back off the wall .. L shape

14. ## Re: Help with slot port.

Thanx thats almost what I was coming up with I guess I was trying to make it harder than what it was.

15. ## Re: Help with slot port.

The min. usable port area was like 84 sq in., would going up about 10 affect it that much?
