I have four Polk Audio DXi 12's, 4 OHM SVC. Right now I have them in a sealed box and I want to build a ported box. I have the specs from Polk on size and port dimensions but I dont want to have 4 ports. What I need help with is converting the 4 ports into one slot port, I have no idea where to start doing the math. Any help would be greatly appreciated.
Thanks |

you need to find port volume of the round ports , i believe its square inches- then do the math for the slot port volume
- a little bit of math and you should be able to get the same Hz rating
