Hi!
I don't think so, it's quite hard to read what they are claiming but it seems it is designed to work above 20khz. That's, in my case at least, super Sonic. I don't see how it could make anything sound better for me. But they aren't too expensive so you could always try.

Well, you have to say, it's a quality-looking product. The Bat$hit supertweeters emerge from the graveyard like the audio-undead once again. 😉
Er -yes and no. With a 70dB efficiency rating (exact rating type unspecified), somewhat daft impedance spec., total absense of anything you might call useful data, and with a nominal operating BW starting from 20KHz (goodness knows what the FR is or how they're rating that either) the short answer for most cases is 'highly unlikely as far as output is concerned.' Electrically, depending on how you hook it up, it may cause some interactions as part of the OA load impedance that could have some audible effects, depending on how benign or otherwise that turns out to be and how happy the amplifier is driving it.

That's correct. With a weight of 1g it can't contain any magnet. And you know it's BS when they claim This is possible because of the Heil-like structure. If you've ever seen a air motion transformer, then you know that's definitely not one, despite it having bends in it. They just can't squeeze any air out.
I'm now in research mode!
The “hypersonic effect” refers to a phenomenon where humans respond to certain types of high-frequency sounds that are above the normal audible range.
The idea is that ultrasonic frequencies, while not consciously heard, may still have an impact on a person’s psychological or physiological state.
The study of the hypersonic effect includes looking at how sound waves interact with the body and brain, beyond just the mechanism of sound perception through the ears.
Now I'm wondering how much musical material has any "info" above 20kHz. CDs go to 22kHz at their theoretical best. Many MP3s cut off at 15kHz. FM stereo surely cuts off below the 19kHz pilot tone.
Last time I checked, I could not hear a pure tone of frequency 10 kHz.
I read somewhere that, to older ears, music has less audible distortion if you use a low-pass filter to get rid of sound that you cannot hear.
Fortunately I have a Rogers HG 88 Mk III integrated valve amplifier that allows me to select low-pass filters of 5, 7 or 10 kHz (12dB/octave).
I think it's time for me to do some qualitative experimentation with something that is quite the opposite scenario to that of adding a super tweeter!

My hearing cuts out at around 10,000 Hz anyway, so no point for me. Moreover, IIRC, the highest frequency which could be reproduced on LP is about 18,000 Hz? Not sure about CD.
The Beatles' Sgt Pepper album allegedly included a frequency in the run-out which dogs could hear, no idea whether that's true, or if so, how it was done.
This looks to me like 'speaker bullets', bags of 'speaker rocks' (yes) and other such things sold in Oz, although at least these don't cost too much: the bullets are $800 and the rocks were $100 per bag.

Galu, if you thought that was pointed your direction, I apologize. I was of course referring to the potential purchaser of such items. 🙂
Cheers.
