KEF T33 rebuild

[profiguy]

Does anyone know the exact quantity of ferrofluid a T33 tweeter uses?

I've heard everything from 100uL to 250uL. I was going to use half of a 300uL packet.

I dont trust the internet on this one judging by the dried up amount I removed, which wasn't that much compared to other tweeters.

Leave out the ff. The world is a much better place without..

As Pete Townshend used to say: 'A Little is Enough'.
Fill the gap to 1/2 to 3/4. That's just 2-3 drops for a 1" tweeter.

@Boden The crossover is designed for FF in the tweeter. I agree tweeters without FF generally sound more detailed, but it also serves as dampening at Fs resonance. The speakers are being restored to potentially sell them, so i want them to be as original as possible.

@jan.didden Yes, it appears I am. Just trying to weigh my options.

I'll probably use one 300 uL packet for both tweeters.

I'd like to add that diyaudio is very different in a most positive way from the "average internet".

I should also add that your contributions (and many others) are one reason for this forum to stand out!
