what are the thoughts of stand alone super tweeter

Ihave been looking into the super tweet subject for awhile.I have no reason to add a pair,from any lack of audible performance,and my speaker is ruler flat to 25khz.

Yet,I heard the Townshends on a pair of Sonus Extrems,and NO person can tell me it was not a HUGE improvement!!

Yet,and yet it is still dependent on the main speaker,and room situation.ALL systems are actually voiced with "room/speaker/amp",and the combination of those factors will determine the success of the final sound.

Since the Extremas(a great speaker,especially with the Townshends)have tweeters that roll off at 17khz,the super tweeter subject is a good idea here,and the Townshends can b adjusted for gain,so it's not a stretch there.

But,in my case I "think" I'd be playing with fire,since I have superb high freq performance,and cannot risk it.

"Except" I occassionally get enthused all over again,when I read about the virtues of hyper extended highs,now "supposedly" available on some of the new domes and ribbons.....Then I'll play some "high freq loaded" program material,and the desire to add something else goes away!

Just my 2 cents.

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.
