I have two 12" rockford fosgate Power 1s. I want to build a ported box and I plan on having seperate chambers to strengthen the box. I was wondering if I could have two ports per chamber to improve the looks of the box. I plan on using pvc pipe because this is my first box and i don't want to go throught the trouble of building a vent. My minmum port diameter is supposed to be 5.6 and the minimum area is supposed to be 24.54 to be tuned at 32hz.
