LOHNT SICH DIE NEUBEFÜLLUNG? | Ferrofluid Austausch am Beispiel einer HighEnd Kalotte | #hifiaudio

I recently disassembled a speaker cabinet that was over 20 years old to check if the drivers were still working. The ferrofluid in the tweeters had dried out. I thought to myself, "These are the perfect candidates to see how a repair works." So let's see if the "oil change" for the tweeters is a success.

I request these from the manufacturer/distributor and usually receive them as free samples. Therefore, nothing is shown "at the request of a manufacturer," but only things that are of interest to me or you. And there is no monetary compensation for this ("money for testing"). The exception is paid advertising, which is then clearly and explicitly declared as such in the video. This serves to finance the channel in general. This is a presentation of my development work and technical information without warranty or guarantee. This is just one example of how it could be built. Any construction or reproduction is done at your own risk. This applies to compliance with technical specifications, operational safety, as well as the success and sound of any reproduction. Any liability for damages is excluded.
