I have a brand new PSW505 I received from Newegg a couple of weeks ago. The foam surround has a one inch section that is loose - looks like whatever was used to seal it at the factory got brittle or was weak to begin with. If I push it back in, it flattens out, but once the sub gets up to a decent volume, that section pops out, so it isn't completely sealed. Does anyone have suggestions as to how to repair this? Some audio video forums I have seen suggest using aquarium silicone to stick it back into place.
