The subwoofer forum isnt working right now so im posting here... I want to build a ported box tuned to 35hz and 2.5 cubic feet. Im not good with boxes and i used an online port calculator so im double checking with everyone on here to see if i got everything right.
The internal dimentions are 30"X12"X12" so that should be 2.5 of cubic feet. Next the port i got was 8"X2"X9.75"
Does this look right and make the box tuned to 35hz?
