Sub making flapping sound

Ok so my mates subs are making a clapping noise(like there is a loose paper flapping around) especially on higher volume. I checked the cone and spider for cuts but cnt seem to find anything. I thing I did notice is the spider looks like its sagging downwards towards the join with the cone. I assume all subs should have have a level spider through out?? And forgot to mention I found his amp gain almost full, no subsonic and bass boost half hahaha. I don't even wanna disclose what settings I found on the headunit lol.. Any quick fix or ideas people

Are the screws holding it into the box tight?

That being said a lot of people's definition of "music" is a clipped 30 hz sine wave with some 80 IQ knuckle head grunting about committing crimes and his genitals.

I had this exact problem, sounded like paper or air leaking, tightened down my sub really good and the sound is gone.

Yah the screws seem to be tight. It makes the sound even when the sub isn't in a box.

I have noticed he changed the tinsel wire. The old tinsel wire was stitched to the spider but the new wire isn't stitched at all

As I said before... Look and see if the tinsel is able to hit the back of the cone...

That's called tinsel slap. A small felt piece on the back side of the cone will make that sound stop. Attach a small round piece of thick enough felt and the noise should disappear.

Im not the one you want to try to troll. Just a fyi for you.

Thanks a lot guys will give that a shot when I meet him.. Was even thinking the sound was from the bottom plate being hit. One more thing, should the spider be level from the basket to the cone on every sub? I have noticed his is sagging down near the cone.
