I have a set of Focal 165 K2P's and the spider completely tore apart from where it attaches to the cone on both of the mids. They run off of an Audison SRX4 crossed over above 100hz and all the settings in the Focal passive set at flat. They are using the airspace of a glassed and sealed door. Anyone ever hear of such a thing?

 

Um, actually the only problem I had with my Focals (165KX's) is the glue let loose on part of the surround. But I just got more glue and all better.

Actually, the surround ripped on my 33vx too. Hmmm. No problems with spyders though.
