[QUOTE="herbykw, post: 4339765, member: 589840"] I am trying to port a home made sealed sub box to specs for my sub. I am running a MA Audio 15" Hard Kore sub in an aprox 6 3/4 CF box--i know the sub calls for a 5.3CF box tuned to 40hz. I am trimming my box down to 5.3 and going to port it. so i have a couple questions.. Does the location of the ports in the box effect the tunning? how can i test to make sure i did it right? Dumb question.. The spec sheet for my sub states the ports shout be "(2) 5X9".. that does mean 2 ports at 5" round and the tube goes in 9"??? correct? The spec sheet has two sets of enclosure reccomendations each with different port sizes and different tuning. Which is louder /deeper 40 hz or 50 hz. Any other hints/tips you guys have?
