    I struggle beyond 14k but feel I'm getting pretty much all there is. Is what I'm missing doesn't seem to be in anyway obvious.

    What's the red to yellow differential on the chart? Does the red denote fundamentals and the yellow show harmonic output? Acoustic instruments can produce loads of harmonics.

    I recently posted this. https://theartofsound.net/forum/show...oke-Headphones

    Seems that even if they are not "audiophile" then they may still have a niche in giving those with hearing loss a chance of improving SQ by boosting the higher frequencies.

    Maybe that's why the kids couldn't hear anything above about 17.5 KHz, limited by the tweeter...or it may be due to me shouting.

    You can download plenty of frequency tests. It is best to test your hearing using headphones as these often have a more extended frequency range than speakers.

    Only pulling your leg Grant

    That's how I feel, don't think I'm missing anything, cymbal decay or something maybe but not "oh where did the mandolin go on that track".

    It is interesting to rotate your head left-right when listening to a tone generator to try and detect differences between each ear and also (perhaps?) the interactions between stereo speakers.

    I am guessing that it is more accurate to do these tests with a single speaker. http://www.szynalski.com/tone-generator/

    I can hear a tone at around 17Khz (albeit at a lower level) but I can detect a tone close to 20Khz when I move my head left to right.
