allright im at the local shop over the summer to have them check on my L7's (the cone supports came unepoxied, they didnt know what was wrong with it) so anyways i come bumping in with my sx 15 and when i asked him to check out these subs and that there was something wrong he says "didnt sound like anything is wrong, those kickers pound!" at the time they were in a 1.8 cuft sealed chambered box i made up for them to make sure they worked alright. so after i tell him that the sub i was running was from resonant engineering, not the kickers he says, psht....never heard of that before, must be like the audiobahns. poor quality and dont get loud. and that box you have isnt made for that sub either, theres only like a inch room between the top and bottom of the sub. i proceed to tell him it is a fine box, 3.5 cubes tuned to 35 hz and he tells me, "wow you dont know anything, you need to tune that at like 20 hz to get the maximum out of that" i keep to myself and he says again, "I'd like to hear how ***** this sub is, cant be any better than the RF p2's we have inside, so i put on some bass mekaniks and he walks away, idk got a kick out of me //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
