steelglam Posted March 30, 2016 Report Share Posted March 30, 2016 Hello, I was thinking of trying to see if the ferrofluid had dried out in the dome upper mids of my AR90s, and if so to replace it, in order to improve their performance. But I have no clue how I would go about doing this, as there does not seem to be an easy way to access the cavity that would contain the fluid. Anybody have any recommended procedures about how to open up the dome upper mids on these speakers so as to inspect and possibly replace the ferrofluid? Thanks in advance for any insight.
