Hi I have 2 12" subs Im going to be selling to make way for my Fi. The other day I pushed one down and heard a scratching noise. however I can only replicate it if i push it down by one of the sides by the rubber outside. When I push it down in the middle by the dust cap there is no sound. The scratching cannot be heard while playing.They still are as loud and sound the same but im not sure if there is an issue. I don't want to be a jerk and sell blown subs to someone and rip them off. Thanks
