ok i understand now thanks a lot for the help

anyone else can spare some help?

I am no sure what you mean rephrase if possible? i am thinking of making a box 35wx17hx20d port: 4wx15.5h tuned@ 36hz with port length 23". that's what the box calculator i downloaded on this website gave me.

anyone? can anyone spare some advice

This type of ported enclosure is giving me a headache to design, yes i know i am a noob but i have to learn somehow, seems i cant find answer to the questions i have, anywhere. First of i downloaded the tuning calculator on here, entered the dimensions and port size and lengths to obtain my desired frequency tune. But i want the slot port in the center between both subs, and that's where i got confused. Like the calculator says i need to bend the port inside of the box. I have seen in pictures that you need to bend the port to either sides in center slot ports, what i want to know is how to obtain that length? Example: if i have a total port length of 28" and i have to bend the port at 23", that bent portion should be 5" in length right. So in the center slot the bent portions on either side would be 5", but that does not make sense to me because it would take up more space in the box, which would change tuning. I also thought of dividing that bent portion 5"/2= 2.5" thus making the length to either side 2.5", this made more sense to me but i am not sure, or am i completely off, can anyone elaborate on this?
