[QUOTE="audioholic, post: 6754437, member: 549629"] He didnt say the enclosure was ported at all actually. Nor does that effect my response beyond avoiding a ported effect in a sealed system, or a quasi-bandpass (6th order) if the enclosure is ported. You simply dont want the area the sound disperses out through, between the enclosure and radiating surface, to restrict airflow, as that would create a porting effect and alter tuning. If the setup is down-firing, and ported... the port AND sub should fire down. Down-fire can be a bit tricky because you want the reflecting surface to be close enough to create a front-loading situation, but far enough away (again dependent on dispersion area) to avoid an unwanted porting effect by restricting airflow. Sorry if my explanation is not clear enough, Ive been drinking. [IMG]//content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif[/IMG] [/QUOTE]
