Let me destroy your bliss....for something you put in a speaker, you should be worried about microphonics.....meaning you need something cast in a box of some kind. Rifa PHE426 is one way to go, but unfortunately not expensive enough to be raved about.

You can also give your caps a good coat of hot melt glue to reduce vibration.

Those caps should be very good for a Xover.

AFter the hot glue tip, I figured I'd show mine. I use that Post It putty used to pin up paper. It's yellow and comes from Home Depot and other places. I just use it to damped the leads as they go into the caps to eliminate as much microphonics as possible.

Here's my Spica TC50 Xovers after I redid them.

Try taking a rolled naked film cap, and mount it on your multimeter with crocodile clips, now squeze the cap between two fingers and see what happens to the capacitance.

The same thing happens in a speaker.

It will not change anything to cover the leads in goo, you need to cast the caps into a solid box or tube of some sort. The only reason to leave caps naked is to get a better markup on them, and as long as we support that, the manufacturers and/or the re-branders will keep laughing all the way to the bank.

All i wanted to know if anyone has heard of or used Claritycaps in there crossovers and if so what were there opinions of them

[HiFiNutNut]

I have bought many of them.

Note that Tannoy and B&W use SA caps for their top of the line speakers.

I could get them at prices cheaper than most sites advertised on the net. Their prices for me were only a bit higher than Solen and substantially lower than Auricaps and many other caps.

I once tried them as the output caps in a very cheap line stage preamp and they did not seem to make any difference in sound quality comparing to even the cheap Mylars (not in a fair test though).

When used in XOs they sound clean to me. Some sweared they are better than Hovland caps.

One day I replaced one of them with some Jaycar polypropylene cap and was shocked that the sound was no longer listenable. I then tried some unbranded Japanese polypropylene caps and the sound was also unlistenable. I swapped back to the SA and the music was back.

I bought 2 pairs of Solen PP for the purpose of comparing the sound to decide what I would buy in the future but have not got a chance to do the actual comparison. I can get both at reasonable prices.

The sizes of the SA caps are subtantially larger than the solens.

I hope this helps.

Bill
