Hey, I have a pair of MB Quarts which do the same thing every so often, particularly at low volume. At least in my case it has nothing to do with any burnt coils or tinsel leads hitting the cone, but rather the pole which the tweeter is mounted on comes up through the center of the woofer, the rim of the hole which strokes the pole for some reason sometimes brushes the pole. In effect, the cone amplifies this scratching and you hear this distrotion type haze in low volume music. What I do whenever this pops up is remove the grill and press downward on the cone about a 1/4" or so a couple of times, giving it a bit extra excursion carefully to unlatch and rubbing. It then goes away. I think the cone material just gets a bit scragly after a while and close tolerances are lost.

*nod* i see whut your saying. On this 6x9 tho its got like felt almost for about an 1/8th to a 1/4 inch wide that covers the hole in the middle. So the actualy body of the cone isnt touching the post. I looked in my trunk and i had a bad speaker wire connection. So i fixed that and i havnt herd it crackle yet.
Another question i have, is on that same 6x9, its got a cross over under the terminal posts. It has 1 larger post for positive, and 2 smaller ones for ground. Which one of these ground terminals gets hooked up? Whuts the difference between the two? any ideas?
