Does inaudible audio above 20khz really matter?

Mike.......I'm certain you meant the title of this thread to read 20kHz, not 20Hz.

I was intrigued by this topic's title, but from the article it's actually: "Does inaudible audio above 20kHz really matter?"

Dan, great minds think alike and apparently we're even in sync!

It can only matter if you sit precisely on axis with the tweeter, as freqs. above 20 kHz are beamed extremely narrowly, due to the increasingly shorter wavelengths as you go higher on freq.
As the frequency increases, the wavelength decreases. Any frequency whose wavelength is longer than the tweeter diameter will be aimed straight ahead in a narrow beam. IMO, there are no tweeters in existence that can go to 50kHz if even a couple of inches off-axis.
Those who sit off axis (which can be anything short of having the tweeter aimed DIRECTLY at you), and claim that the sound is better, are DEFINITELY NOT hearing the higher-than-20 kHz freqs. at all, unless they also have a tweak that changes the laws of physics.
Sitting directly on axis of the driver, I have used super-tweeters that went up to 50kHz or so, and I thought they made a difference when aimed directly at me. Ultimately, I found that I preferred the system's musical involvement without these devices. YMMV...

I recently added Townshend super tweeters to my Quads and I like the improvement, it has significantly enhanced many recordings w/o adding any deleterious effects. The 57 def benefits from them as they nose dive beyond 15khz or so. A listening buddy of mine has Tannoy Churchill wide bands with the super tweeter and the effect is the same. We both preferred it with the ST in the circuit rather than not, esp with analog sources.
