Tweeter Capacitor Upgrade (Coincident PREs)


Hi all, looking to upgrade the Solen 4.7uF 100V caps that filter the low frequencies out of the Accuton tweeters on my Coincident PREs.  Started by looking at Duelund's, but PartsConnection doesn't even list prices for a lot of the models (or is out of stock) at that value... that motivated me to try and collect some impressions from the group.

Apparently Isreal is using Mundorfs in that position at this point.

As always, thanks for the input.

Hi @cal3713,

I did experiment, I compared sound of my speakers with only Duelund RS 3.9uF in HF crossover and  Duelund RS 3.9uF bypassed by Duelund Cu-Sn 0.01uF.
9 month time ago when I put  Duelund RS to my crossover it hadn't passed break-in and Duelund improved the sound a lot.
Now results were different.
Without bypass sound of instruments has better focus and a little bit cleaner.
On other hand with bypass tone is more savory and vivid. In comparison Duelund RS without bypass sound more lean.
In general, I like sound of my speakers with bypass more.
Yes, bypass has some drawbacks, but it is also depends from specific type of capacitors, system and listener. If money wasn't for me an issue I would use Duelund Cu-Sn 3.9uF  without bypass capacitor.

Regards,
Alex.
