I remember the Coleridge well - absolutely magical sounding mid and top but they did not suite Rock music well for some reason I could never quite identify but may well have been the bass timing being a bit off. I'm sure they used some type of ceramic tweeter, not metal, it was bloody good though.

My Celestions use a titanium dome that is not at all sharp or harsh despite what HFW said in their review (if you are reading this Mr Price;)) but it does give a 'generic' sounding top that is a little disappointing on occasion and is the main reason I will have to be 'moving on' 'speaker-wise at some point. The tweeters on my neighbour's Ruark Talismans are far better - they are some sort of soft dome.

How high? My titanium tweeters cut in at 3KHz

"very clear treble with sparkle" characterises my speakers well.

I have never considered them harsh or brittle.

They are! Both tweeter and midrange are beryllium, the tweeter a conventional convex dome and the mid a concave unit. The two together give a completely seamless presentation, not harsh but very detailed and extended. Voice is natural and the extreme treble reproduces sounds like the triangle very realistically, even from CD (not the best source for extreme treble).

Usher have continued to develop the tweeters. I know this because my son over-drove the speakers about six months ago and blew both tweeters. Hi-Audio, the distributor, ordered me a replacement matched set from Taiwan and I swear these replacements are even better sounding.

Mine have titanium tweeters and aluminium midrange units - they are as big as a tennis ball - a big domes.

Best tweeters I've ever heard were Dynaudio Esotar T330D, which were used in stuff like the Sonus Faber Extrema. Once had a pair in a previous incarnation of my current speakers some years back. they were awesome, but at over £500 per pair, a tad pricey

You can't get them now as Dynaudio don't sell to the DIY market anymore.:(
