Amazing speakers, however, what are these oily marks on the tweeter, is there a chance it is ferrofluid? It was like that since the moment I unboxed them.

    That would probably be from ferrofluid. Especially if they were in a hot environment

    Is it going to have ANY impact on sound quality and performance generally?

    Oh yes! Totally loved them! I mean, are they going to degrade somehow sooner because of this?

    Maybe in the next 20 to 30 years

    Ferrofluid is made from microscopic ferromagnetic particles along with a carrier, usually an oil. The ferrofluid is attracted to the magnetic field of the driver magnet, meaning it sticks to it like glue.

    I think it's highly unlikely those stains are from ferrofluid migrating.

    The speakers have old manufacturing dates. Almost 4 years ago. If they were stored incorrectly or if the box was placed with the tweeters facing down, it might not be that difficult for a small amount of oil to run down its fabric.

    This video should show why that's unlikely
