Supertweeters

[CageyH]

A quick back to back with the STs taped to the back of my speakers and it seems that they make a subtle difference.
Bass and miss seem more detailed, and there seems to be more "air" in the soundstage.

I need to try them pointing forwards, and in the horn mouths to see what I prefer, but it very much looks like I will be keeping hold of these.

The BatPure cost me €53 delivered.
Are they better than the Tannoys? I doubt it, but they are probably good enough to see if you like the effect of the super tweeters.

I've tried the BatPure and a few others and I find the ST200s work best with MGs

When i tried them, i perceived an effect on bass too, although i was informed by the informed that this cannot happen.. still, it did in my view.. Overall i preferred the system without them. Still have a couple of sets lying in shed unused... ribbon and horn i think. One boxed set i used were sold to someone on here...

Off topic but if you've still got these Grant can we come to some arrangement?

Alas both were sold Andrew

Hey ho, I shall buy some of the Philips ribbons from that auction site and have a play.

Related to this topic I took delivery of a nackered pair of Mordaunt arundels today. I took the romagna crossovers and Kelly ribbons out and stuck them on top of my wharfedales. Listening to Eva Cassidy now every little nuance of her voice and breathing is coming through. Obviously not supertweeters as they are crossed over at normal tweeter frequency but very exciting, now I just need to make a box and custom crossover. Any help appreciated!

The Decca DK30 ribbons work superbly as supertweeters. Just roll them in high with a 0.5uFd or 0.22uFd series capacitor. I know this works, as It's setup I had with my Tannoys years ago.

Thanks but does that protect them enough I read somewhere an 18db/octave slope is best. Although I guess if you crossover high enough first order will be ok, do you happen to know what frequency those values correspond to?

They'll be fine. With capacitors that small, there'll not be much signal reaching the ribbons below about 12kHz. An 18db/oct slope may be handy if you're supplementing something like the Celestion HF1300, which has a very steep top cut off, but a shallow slope is OK in most situations and would likely sound smoother too.
