what are the thoughts of stand alone super tweeter

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.

1 of the problems with super tweeters is they are designed to work with many loudspeakers so thus they never are fully matched or fully integrated to any unless you get lucky. Best to DIY or have one custom built to match your loudspeakers. You wouldn't just use any tweeter and crossover type if you needed to replace tweeters in your loudspeakers you would contact manufacturer or find best match to the speaker, but with super tweeters you just buy a one for all design? this not optimal at all. At least with subwoofers they have own amplifiers and fully adjustable networks but with commercial super tweeters your lucky to get a switch to adjust 2 setting or a cheap pentameter to match levels.Most don't even offer this. And if ST is properly designed for your loudspeaker you shouldn't need anything to adjust, level or crossover.Just move ST forward and back to set up time alignment.
