Erik, I asked you a while ago, but you never answered. I read your paper on a pair of speakers you built, but asked how many pairs you have actually assembled? Is it the one pair, really just curious, I am not handy and wouldn't dare try.
Dried up Ferrofluid?
What causes ferrofluid to dry up? Heat, usage, age? Is there a usual shelf life, as in, do most 15-20 year old tweeters that originally used ferrofluid, need new ferrofluid?
How is it checked, where is it bought, is the replacement generally the same from tweeter to tweeter?
Thanks ahead of time for any info regarding this! I figure that there are quite a few good speakers out there that are getting up there in age so this may be something I’ll want to learn to do!

Sorry erik, I must have missed your answer. I wouldn't have expected you to build the cabinets, a whole other deal requiring the woodworking tools. Just buying a kit with all the parts preselected by someone else seems adventurous to me. As I mentioned, I am not handy in this way. I have read several articles by people who have built speakers (not the cabinets) and the tuning via crossover part selection seems not for the faint of heart. |
Dried up Ferrofluid? I posted this up 6 months ago, why some were complaining about harsh Thiel tweeters that get non-linear distortions with sticky old Ferro Fluid that’s gone like tar, it has to be cleaned out, just don't add new fluid to a gummed up voice coil gap, you'll be wasting time and effort A lot cheaper than buying new diaphragms. $10 for new fluid vs up to $200 each for new diaphragms, and they could be clones/fakes. Still have to clean out the old fluid doing either. Tweeter Ferro Fluid and how to change it. https://www.parts-express.com/ferrofluid-100ul-general-purpose-for-1-diameter-vc--340-540 https://forum.audiogon.com/posts/1843203 https://www.speakerrepairshop.nl/en/instructions/replace-ferrofluid-in-tweeter/c-36 Cheers George |
@jetter If you can drill a pilot hole straight, and add glue you can build a kit. Here's one of the simplest kits out there, get your hands dirty and then after you may not think it was all that difficult. :-) https://www.madisoundspeakerstore.com/2-way-speaker-kits/seas-a26-10-2-way-kit-pair-based-on-the-cla...
