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.

Also does anyone have any experience with these subs and can provide feedback on them
