Joe X Posted August 17, 2023 Report Share Posted August 17, 2023 Just going by the subs manual for each subs you need 121 liters and 41,2 square inches of port area tuned to 30Hz So the box need to be 242 liters net and 82.4 square inches of port area at the same tuning. So how you get 82.4 square inches with 6" round ports, one 6" round port is 28.2 square inches and 3 are 84.2 almost exactly what is needed so: 3 6" round ports is what is needed according to manufacturer specs based in a 242 liters box and rated power. Since you are overpowering you probably need more port area but at least you do need 3. Quote Link to comment Share on other sites More sharing options...
