what are the thoughts of stand alone super tweeter

I am well aware that the Ionic driver was not a super tweeter as such. My point was that it went out as far as a typical super tweeter, did not require a crossover to a tweeter as it went low enough to mate directly with a cone woofer/midrange but still , despite the best efforts of B&W, was not totally satisfactory. I have seen any number of revolutionary tweeters and super tweeters come and go over the last 40 odd years. The problem has always been matching them to the rest of the system. My speakers are also flat out to 25k and I must admit to being puzzled as to what extending it to , say ,40k would achieve. I would not be the best judge in any case as my ears will no longer hear 16k.

Stanwal, I can just hear 16K and my speakers are supposedly good to 40k Hz, I too have had several tweeters and super tweeters, but the Murata demo was my first real experience where I had to have them. I have to assume that their having no music they reproduce is the key. I have also to assume that information beyond our "hearing" is contributing to our pleasure.

I am having trouble with the concept of " having no music they reproduce" . Surly they must be reproducing the overtones of music in the audible range. Otherwise we left with the notion the simply stimulating our hearing beyond the audible range is somehow pleasurable. I have been using Spendor speakers [as well as many others] since 1971 and I well appreciate the value of a WELL Integrated super tweeter. At this point I declare "De Gustibus Non Disputandum Est" and retire.

Stanwal, nevertheless at the demonstration all we could hear was pops, etc. Most of us, as I said, did not notice that they were on and still playing the music. As I said there is at least one study that I have read that shows an awareness of such high frequencies, but off cd how do you even get these frequencies?

I too will rest my case, but I think the lowest frequency that a super tweeter is key to its benefit in the system.

It if funny how some can embrace changes a copper wire can make but then refute the concept of a supertweeter.

I also find it funny that Kal is looking for "independent corroboration" when it is right here in this thread and in audio magazines. This is as much corroboration as we'll ever get.

Ditto for the impact different cables can make. There is no scientific proof! We just make our own independent analysis using the finest test equipment in the world - our ears.

My personal theory of explanation is in line with Markphd's. It must have something to do with interaction of the sound waves - and not necessarily the sound waves (or frequency level) coming out of the tweeters.

I am anxious to try a pair of supertweeters one day and see for myself what difference they make.
