What do type R's like for port area

[plugger 10+ year member]

Just got 2 new 12" Alpine type R. Ive done research and come up with net airspace of 4.25 for both tuned to 33hz. What port area should I aim for? Will be powered by a kicker zx1500. The subs are both dual 2 and the amp is 1500@2 so it works. Thanks.

type r's like alot of port so 18"^3 per ft is usually good for them

I would do around 4 - 4.5ft^3 net volume and around 60 - 70 in^2
