Truk993 Posted February 6, 2020 Report Share Posted February 6, 2020 I’m building a box for (3) HDS 2.112 dual 2 ohms. Box size will be 5.25 cubes total for all 3 shared. Looking for box tune 34hz. I’m doing 2 square ports 3.5”x3.5”. Calculators say I need roughly 8” port length each. This sounds kinda short, is this correct? Thanks for any input.

CrackFactory Posted February 6, 2020 Report Share Posted February 6, 2020 It's short because your port area is super low. You only have 24.5 sq in. I would go with at least 60 sq in if you're running them at full power. Link to comment Share on other sites More sharing options...
