thanks but we can read ....more info are never wrong and are really on topic, read post 15

nice one ~13bux in stock MKP1848622454P4 Vishay / Roederstein | Mouser
rated at 40V/us = 880 Amps peak I reckon they should handle anything your amps can throw at it.
I guarantee this part would kick any audiophile cap to the curb in real testing. The machines used to flame spray the end caps would stagger any mom&pop operation/

interesting ERO Roederstein is audiophile approved. are they crazy?ERO Audiophile Capacitors
hmm wonder how much could I charge 22uF 450V

No need to assume, the 1848 series is intended for high current industrial abuse.
(also developed for Xray power supply duty)

I suppose the difference between 'reckon' and 'assume' is a thin OT line to cross.
At least we (may) agree that it would be fun to see the Xmas tree all-side decorated with MKP1848 presents.

mods/ just when I thought I was helping someone, now I'm lost in the land of quantum entanglement.
can audio amps source or sink 100's A of current?

What do you mean by "tweeter protection"? What are you trying to achieve? 22uF seems like a rather large value for a typical tweeter x-over.
I assume the Beryllium tweeters are high quality drivers (ScanSpeaks?), so a good MKP capacitor is in order. I commonly use the Mundorf M-Caps, and I prefer them over Cornell-Dubilier, Vishay/Roederstein, Clarity, etc. with respect to sound quality (as tested using my subjective ears).
I get my M-Caps here:
Strassacker, Komponenten: Lautsprecher, Frequenzweichen, Bauelemente
Shop
Just pay attention shipping costs, which will depend on where you live.
since I'm now able to assume more freely.
yeah it's in the loungei'd surmise he wants DC protection from gross amplifier failures rather than some other kinds of mishaps.
drunken operators etc using active Xovers controls
ohh ear testing tell us more, who needs data sheets anyway when we have our ears
I love those audio companies caps they can source them from anywhere and put a label on it. and yer left with their marketing images of loving hand-crafteted parts from workers with souls, not robots on assembly lines.

Then a DC sense with a relay switch would be better and probably also cheaper than a capacitor in series with the tweeter. I recently bought some of these kits (UPC1237 DC sense with relay switch), and they seem to work well.
K thanks for the OP
AFAIK mech switching isn't as fast as a series capacitor , esp on a tweeter, it doesnt take much time for damage. woofers maybe OK to survive depending on other factors like max. excursion . in other words normally speakers already have series tweeter caps in their PASSIVE Xover, the OP maybe relying on direct connection with a big crude 22 uF DC blocking cap. E.g. active design.
if it was me I'd use a much smaller cap and incorporate it as part of the whole transfer function , als lil more finesse.

Maybe a higher end automised winding machine can be programmed to introduce random variations in tightness of the winding. Just a few extra lines of code...
like is said above> the key is how the lead to foil connections are reliably made. it's a simple but demanding process not many have the know how, machines, and secret sauce. does he need 40V/us probably not
I have never experienced a driver dying from excessive mechanical excursion, but I have seen them dying from overheating voice coils due to too much (DC) current. Overheating takes a moment to happen, and the response time of the protection circuit can be set to a short value for the tweeter, which will probably never see any low-frequency signals anyway. If it was me, I'd this route in a system that does not need/have a filter capacitor between the amp and the tweeter (active speaker or similar).
I'll take a robotically assembled and tested part ANY time over a "hand made" one. Far more likely to have the process under control.
echi, ni, san, shi >most all "hand crafted" by harassed china workers and guy at the end still reading the book on QC.
got the robot sounds from Kraftwerk on my mind

I bought a set of 4 Tannoy Leopards. All four needed new fabric surrounds. They were torn, some only short tears and others quite long tears. I suspect this was due to repeated overdriving in a PA environment.
I fitted roll rubber surrounds as replacements.
