Ribbon Tweeters

A while back there was a thread on new ribbons, like the Ravens. Not much interest. I wish someone could give us a review of the ESg 2&3's the Ravens, the Philips RT8 and RSQ8P/11's. Yes ribbons have been around forever you say , nothing new about ribbons. There must be some advances. There are the new better dome tweets. Some Agon member has the Raven 3's($3400/pr.!!) in a design. Wish he could give us the review.

The reason I asked is because I'm thinking about testing the Piega's and want to know if is going to be a waste of time. The dealer representative will bring them to my house so I can hook them up to a Rowland and Meridian combo. But, I figure why bother if ribbon's are not accurate.

Rory, I *think* the Piegas roll-off higher than 20kHz... (Heard the 10 once & was impressed, BTW.)
Also, I have not experienced any tonal/ phase/? inaccuracy listening to ribbon tweeters -- but that's just me, no ribbon "guru" here!
OTOH, is the Rowland wide-bandwidth? (I don't think so) Why worry about signals over 20-30kHz if the amp doesn't output them -- or am I missing something? Cheers!

Piega speakers extend to 47.5 k.

The lack of extension beyond 20khz isn't/shouldn't be an issue since less than 1% of the adult population can even hear above 20khz (or actually: 1% can hear to 25khz). The fidelity laws are still set at 20hz-20khz as being one of the the ideals for speakers. Your concern would be just with how they perform in the same territory-below 20khz. That being said, its really how well the technology was done-there are good ribbons and bad ribbons (e.g. single-ended). I would go ahead an audition the piega's. There's not alot of musical information above 20khz either. Some stuff like cymbals contain harmonics as high as 100khz and studies have show that when exposed to stimulus' above 20,000hz there is/was brain activity, but no listeners subjective evaluation was able to detect the stimulus even though it was happening to them. I don't think it would be "a waste of time." Ribbons can be good. If you don't like them it would probably be for all sorts of other reasons, like distortion levels or something. Listen to the Piega's and some other stuff in the same price range to get a feel for what you like. And don't feel pressured by the dealer even though he is doing something nice. Its an expensive purchase and you want to be happy with what you get-trust your instincts on it.
