Subwoofer enclosure design questions

I am working on designing an enclosure for my 1971 Chevelle and had a couple questions. I don’t know the dimensions of the box yet but I am trying to plan the internal sections for it.

The subs I am thinking about running are Digital Designs 2510A I plan to run two but have sealed sections between them

These subs want
1.5 cu ft
23" port length
24" sq port area

Can I design a port that goes down one chamber then curves back and comes down the opposite side of that chamber? Would the sum of those lengths be the port length?

example a port is 12" h 2" w and goes down a port of 10" then it makes a 180 degree turn and goes down a port of 13". Would this work or would it mess with the sound?

Any other recommendations when designing a sub box are welcome. It will house 2 subs and 2 amps

That port configure ration should work fine. I had a port in one of my old boxes that went around all three sides of the inside of the box. Please see attache ruff sketch and notes.

Did youmean 90 degrees instead of 180 degrees???

It is not the “shape” of the port, it is the volume of the port that is important, although you do not wantto interfear with air “flow” in the port, it can cause “port noise”, any inside angles should be rolled,do notleave sharp edges.94

Thank you for the replies but I think i’m going to go with a sealed enclosure
