so i finished my box last night and hooked my subs up and low and behold one of them makes a god awful noise when playing low and turned up to a certain volume. kinda sounds like a goat baaahhhh:mad:
the cones are all black. there is the s logo in the middle. sorry no camera. the stickers on the back have been removed so there is nothing on the back of the speaker. i was told that these were bought a year or so after they came out.
so i got two speakers from a buddy of mine but there are no stickers or anything on the back. he doesn't know what they are either how do i tell the difference?
i am currently making a box for two l7 12s to go under my back seat. the majority of the box will be mdf, only half of the bottom will be fiberglass. so how many layers is enough???
