Yeah it’s junk pretty much.
If the cone moves freely without the coil rubbing (but sounds okay when pressing on the cone and it is playing), might be a bad tinsel lead or solder / crimp connection under the dust cap. Not a simple repair on a sub like the kicker. Could carefully dissect it, but not a simple task if unfamiliar with such a project, and likely have to actually cut into the dust cap to access it with the cone design.
Otherwise, yeah it could very likely be blown as well. Take it out of the box, inspect the wiring / terminals / tinsels, but probably not much hope for it.
