Question for you experienced speaker or crossover DIYers.
I am using Caps only to protect tweeters paired with a Fast-15 drivers.
Does the quality level of protection Caps on tweeters improve SQ?  Is it worth spending $’s on top quality Caps? Thanks

Like Donnie….i am far from an expert but went down the rabbit hole with modifying the caps and resistors to my Decware ERR speakers as well as a pair of my Pinnacle bookshelf speakers.  

I would say that if you already have a revealing system… Then the capacitor addition at the speaker will be noticeable.   It’s really up to you to decide how crazy you wanna get with the capacitors.  I can tell you that I spent a good chunk of money on my capacitors, and it really transformed the sound to a level that was eye-opening.

Here is a link to the thread that I posted about modifying the capacitors on my speakers.  I would say to start from the most recent post and work backwards. The first two or three pages were from other forum members who had already paved the way for my exploration..

Also… take a look at this website from the humble homemade hifi.  He gives a very detailed description of a lot of capacitors and how they sound. I used this as a guide when I was trying to decide which capacitors to use.  I found it very helpful along with the guidance of forum member Will, who is by far probably the most knowledgeable when it comes to this topic.

Just remember that whatever cap you purchase, to make sure it’s wired up correctly.  For some caps it doesn’t matter…but for others it does.   After you determine the signal path the main cap, check the markings on the new cap.  Some caps are marked with a hash mark, a dot, or some other identifier on the casing.  Other caps use a shorter wire lead on one side of the cap to identify the input side of the cap.  

Also…if it’s a bidirectional cap…you could temporarily wire up the cap with alligator clips.  Listen to the sound, and then reverse the leads.  See which way the cap sounds better.

FWIW….i used the Jantzen cap when I modified the crossover in my Pinnacle Bookshelf speakers, and I really liked them.  The  Jantzen’s are a good choice.
