I've never seen a side shot of an assassin before, so it might be made like that, or it might have come unglued.What you see is the voice coil former.
Have you tried pushing down on the cone to see if the spider moves with it or not?If the spider doesn't move when you move the cone, chances are it became unglued or wasn't even glued in the first place.If it does, it was probably made that way.I'm not too familure with the way they're built.
just one? hmm. was it performance effecting? the marks are from this plastic piece they had on top of the sub for shipping. it just creased into teh gasket.One of mine was like that too. That box is not too small. Whats with the marks on the gasket though? Looks like it's been used.
