SUPER TWEETERS-anybody heard them?

I have a pair of Tannoy ST50 supertweeters on my Verity Parsifals and absoultely love them. Suprisingly, the imrovements are not so much in terms of added sparkle (although the treble does seem to extend higher up and seems more delicate and nuanced) but an overall sense of liquidity in the sound. The transients are also cleaner and quicker. A definite improvement, well worth the (steep) price.

The super tweeters I used were rated to 40kHz. But you are correct when feed with enough power they are very nice and obviously do not need the super tweeters. I still have them with no plans to part with them. I do need to buy new woofers for them though.

I just checked out information on the Tannoy supertweeters, and was surprised by the high price. Considering that you can get a decent tweeter that goes to 20Kc for $100 or less, why should it cost so much more to extend to 30 or 40 Kc?

Seems to me that piezoelectric technology is perfectly suited to this application, and piezoelectric supertweeters are made. Their low cost may be an embarassment, but do they do the job?

Viridian...thanks for the info. I figure the wavelength of a 30Kc signal to be less than 1/2 inch. Even if the Piezo driver were perfect regarding phase, how could one ever get it time-aligned with the other drivers of the system? Maybe the phase problem isn't important.

If I were to try out a Piezo, is there one brand that you would suggest? I would just hide it behind my MG1.6 speaker, and bounce its sound off the ceiling.
