FerroFluid aging
I know the topic has been discussed previously but this one is a tad more specific.
Did B&W use ferrofluid in the 800 matrix (801 - 805's) series (1-3) tweeters?
If they did, is there any known issues with the drying out of the ferrofluid in the 800 series specifically? Yes I had some Vifa tweets that it happened to, but sadly my 805's died from other causes so I don't know if they would have lasted.
Any info would be appreciated.
Thank you for the link, however, that is the one tweeter in the 800 range that is not the same. Even the link to the 801 s2 doesn't specify FerroFluid or not. But after seeing it in the 1,25" tweeter I would "assume" it is in the 1" also. https://www.stereophile.com/content/bw-matrix-801-series-2-loudspeaker-specifications
