no noise! im still impressed to this day what kind of a difference the enclosure made. sh!t makes me go deaf man. my neighbors have yet to complain though, only my family complains //content.invisioncic.com/y282845/emoticons/smash.gif.499e08a4a35ffaf54f4c8194fb8fe8ed.gif

i think if i ever were to go solos again (which is unlikely but not out of the question) i'd get 4 8's (not to be a biter lol) but because they require the same internal volume and would theoretically perform much better. of course driver displacement would affect it a lil but eh.... point is im never goin sealed again lol
