I met Max Townshend at the Premium XFi show in Holland where he had a demo going on 2 pairs of identical speakers, one pair mounted on his platforms and the other pair on spikes adjusted to equal the heights, it was impressive. Basically he is isolating the speakers from mini seismic tremors (his explanation)
Equally as impressive was the demo of his super-tweeter. Adding the device improved more than just the very high frequencies. It was producing the upper harmonics of all instruments allowing them to sound more real.
A lot of you will be shouting ’but I can only hear up to 14Khz’. Well it doesn’t work that way. The harmonics contain much of the spatial information and provides clues to the performers relative position. If you hear an instrument that has had the harmonics removed you will be listening to a pure sine wave. Does not matter if it is a sax or guitar, if they are both playing middle C for example what you will get is a pure tone at about 262Hz. Now when the harmonics are present you are able to identify the instrument and it follows that the more faithfully and completely the harmonics are produced the more a piano will sound like a piano. It’s quite uncanny when heard.
Taking cognisance of the above it will be easier to understand why room treatment is so important. If all this info is left to bounce around the room unhindered the very fine detail (harmonics) is just a jumble, confusing the imaging and making it harder to identify vocals and instruments.
OP, I apologise for going off track but Townshend’s name triggered my memory.
