hey guys i need help designing a sub enclosure for 1 10" cvr. im not sure what would be good freq to tune to im thinking 34 hz?

anyways here are the specs
english (metric)

fs 33.2
Sd 58.7 (.0379)
EXmax .501 (12.73)
Rd 6.71
d 2 (50.8)
Qms 8.93
Qes .640
Qts .597
Vas 1.42 (40.24)

manual says vol should be 1.75 cu ft + port displacement

let me know if there are any other specs you need....

lastly if its not too much trouble it would be great if you could design a box for 2 of the same subs

THANKS

so to get 39 square inches of port area you would need 13 high x 3 inch wide port opening

1.75 cubic feet would be even better ported to 37 hz if you have the room

gave you three boxes to choose from plus a single 10 box the 3.70 cubic foot box for two looks to be the best possible outcome
