Mundorf supreme silver/oil

[Salas]

Hello,

I checked this cap in a 3 way design of mine with Eton speakers.
I changed the Tweeter cap (was an SCR) to the Mundorf supreme oil/silver.
Never heard such a good cap before a tweeter (and I have checked many). The amount body and 3D without harshness is socking.

There are lot of good caps however the SCR or low grade Polypropylene. So it not suprising that the sound improved.

I used the .47 uf Supremes as coupling caps in my 300b mono blocks.
They are very nice.
I am in the process of putting together an order for my tweeter and midrange crossovers.
At about $300.00 for each speaker I am really hoping they do for the speakers what they have done for the amps.
Buying the Mundorf’s has ruined me for other caps. It would be nice if they went up higher than 10uf. 15 uf would be very nice, but very large I‘m sure.

In the future I will be using them anywhere I reasonably can.
For now...I scheme and plot... to acquire the 160 or so, 10 uf caps it would take to do my woofers over.

Currently I am busy making a sign that reads
"will work for capacitors".

Hi,

I'm only replying because you carry that lovely tube in your avatar...kidding...

The amount body and 3D without harshness is socking.

FWIW, I feel they're about the best money can buy...
Second best are the Siemens-Epcos to my ears....

Cheers and happy tweaking,

Frank,
Are you talking about the Siemens-Epcos Motor run B32328 series?
These would come in reasonably high values (up to 60uf).
Thanks

Cheers,

Note not all cap are design for using in speakers. When selecting a cap for a speaker you should be looking for a cap capable of handing high currents. Polypropylene come with different film thickness and the thicker film being better for high current.

These are some of the best caps sold in the US.

TRT's DynamiCap: metallized capacitors Low current signal Cap
Reliable Capacitor: Polystyrene & Polypropylene Foil Makes: High Current and small signal.
Crescendo’s Polystyrene: Foil and Metallized High Current speakers and small signal.
Component Research Corporation, CRC Teflon & Polystyrene and Polypropylene Small signal
Hovland Film & Aluminum Foil Polypropylene High Current.
Sprague 735P: Polypropylene Tubes and Small Signal.

I have tryed all these cap and the are much better than the Wima's, Roderstien.

I just have not tried motor starter caps in speakers seems to strange, with their funky size poor lugs. I'll stay with quality film for signals

Cheers guys,

It seems there is a reason they went so well in loudspeakers. They are designed and listened to with that in mind. They must have thick paper cause they can run @ 1200VDC. Very bulky too.
They got sweeter after a couple of days not to forget mentioning.

What do you think is used for material in motor run caps ??

Hi guys!
We have tried some old 4uF PiO cap's (ISKRA) from an old rectifier in Avantgarde horn speaker and they were doing just fine (before there were some polyprop. in it...)
