i noticed today that my sub making a rattling sound and hit noise when i crack the volume up.
i didn't touched the gain for a while and the noises come when i am on high volume.
it wast like this before i must say.
so i took the sub from the box to see i i can hear from where this noise is coming.
didn't hear nothing special i noticed that one of the leads is kinda touching the cone and there is
leads marks on the cone.
when i play the sub all volume up on free air i don't hear hitting sound only low rattling sound
when i put it back i can hear something hitting or hitting sound and rattling on a bit low volume.
Ive also checked the cooling hole on the bottom if there is a FOD in it didn't find nothing and the sub looks aligned.
what can it be ?
is it possible the spider lost there stiffness and i am hitting now the XMAS ?
Or is it the box fault ? too much port area ? or the port area is too little ?
