porting?

[jackson 10+ year member]

can pioneer impp 12's be used ported.always been told they are for sealed enclosures only. If they can , the specs call for 1.5 cuft per sub, what size internal dimensions would I have and port size? keep in mind I want LOW,LOW BASS around high 30's low 40's. My sealed box sounds good but I want the low bass to be felt.//content.invisioncic.com/y282845/emoticons/banghead.gif.8606515f668c74f6de0281deb475b6fd.gif :banghead: //content.invisioncic.com/y282845/emoticons/banghead.gif.8606515f668c74f6de0281deb475b6fd.gif :banghead: //content.invisioncic.com/y282845/emoticons/banghead.gif.8606515f668c74f6de0281deb475b6fd.gif//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
