Hi everyone,
Long time reader of this thread here, but first-time poster (: I was hoping for some insights on the following: I recently exchanged my CS1.2s for a pair of 2.4s. When I brought them home, I noticed a sort of brown residue were the surround meets the cone of the mid driver. It looks a bit like ferrofluid. I'm wondering whether this is just something that happens to these drivers with as the glue ages, or whether it means my driver needs servicing or has been tampered with. I'm especially curious because to my surprise, the 2.4s sound a bit brighter than the 1.2s, where I was told they were one of the more mellow-sounding Thiels.
Any insights would be greatly appreciated. Here's a link to a picture of the driver and the residue:
