Super Tweeters - Fact or Flights of Fancy?

Whoa, come on chaps ;)
Improved high frequency is a possibility although I would still argue that a decent pair of HF drivers will cope with anything that can be dug out of the source; extended bass…..well it’s just not possible.

Super HF drivers may help bring up the treble response, especially for those of us who are, erm, getting on a bit.
But, adding to any frequencies that can/are already produced by the “normal” HF driver may sound better but it will put a hump in what may otherwise be a flat response.
Good sounding maybe; accurate reproduction it isn’t.

Used properly like in the Harbeth SHL5's I think they work really very well indeed. They don't put something there that shouldn't. Nicely balanced.

So what do the brainy and knowledgeable folk here think of these? Fostex. Worth it on a pair of Spendors?

If you are only listening to CD then don't waste your money ;)

Well basically yeah (cds ripped to flac). How disappointing. I was really buying in to the whole concept. Ah well more money to spend on the new tv I guess ...

I imagine someone already said this already (Reid alluded to it); I just didn't have the wherewithal to go read the rest of the thread:

If your source isn't providing (musical) information above 16-20kHz, you probably don't want supertweeters. If you're a super cool SACD fan, then hooray! You won't 'hear' the information, but you will hear the audible band information modulated by the newly introduced upper harmonics. They're what makes the squiggly line even squigglier! :eek:
