Ribbon tweeters

Why does Madisound say ribbons should be used with passive XO?

Why is active no good for them?

- Fragile ribbon element. Yes the ribbons are very fragile. You do not want to blow directly on them, and they require steep crossovers usually 18db (3rd order) or above to protect them from overexcursion. It is also absolutely recommended that you place a capacitor inline with the [ribbon] tweeter to prevent them from being damaged by turn on/off noises etc.

Active is fine. Just add a capacitor for protection.

Consider it a condom //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

It's just not ribbed, for her pleasure......

because your amp will see a dead short if you try and run the ribbons without a passive device on them.

Is using a cap inline with your tweeters almost always a good idea when running active?

I assume we would choose a cap that filters out frequencies far below where we would normally cross over the tweet but high enough up to prevent the relatively very low freq's that can easily damage it?

You could consider it a safety feature should your amp blow and send straight DC to the tweeter. The audio snobs may bawk at you for doing it tho.

You can go either way with cap size - a few octaves below your xover freqency or way up beyond the hearing range.
