RE: "I am likely going to triamp my ribbon tweeters of my 20.1's" ...

If you actively tri-amp, yes, the ribbon amp will be directly connected to the ribbon. So the issue is ... is this risky behaviour ... or not? Should you put a series cap in ... or not?

I have been actively tri-amping for about 15 years - for the last 6 years, without any fuses - and have never ever blown a ribbon.

However, I suggest it is best if you have an amp which does not make a loud turn on/off 'thump'. Interestingly, enough, the ribbon amps I had been using for the past 6 years, while they didn't make a sound ... when I recently looked closely at the ribbon (with someone else switching the amp off) I saw that the amp caused an almighty convulsion in the ribbon! :-(( But this must look worse than it sounds as, as I said, it never caused a ribbon to blow.

I have just installed new new ribbon amps - these are much gentler on the ribbons - they cause the ribbon to twitch ... but not convulse like the previous ribbon amps. They also will cope with a 2ohm load - so I'll now remove the 1ohm Duelunds that I currently have in series with the ribbons.

So I would say series caps can - and should (for better sound) - be done away with ... but you have to be careful with your choice of amps for the ribbons.

Andy
