Eh, I dunno. Ferrofluid sounds pretty good compared to melting Mylar. It's just another case of don't use it if you don't need it.

Right, if you don't need an Esotar you don't need ferrofluid...

I hate to rain on anybody's parade, but Troels Gravesen mentioned that ancient JBL cone tweeters (25?) worked better than anything else in a waveguide when he was experimenting with the TQWT.

But being a modern man, he needed something more currently available.

Not a whiff of ferrofluid, of course.

Also, interestingly, the two most genuinely liked modern tweeters, the Vifa XT25 and SB Acoustics ring-radiators don't use the stuff either.

It's easy enough to add some attenuation to a tweeter filter to tame any Fs resonance issues.
