I'd like to add to Als explanations. I do believe that ultrasonic frequencies do influence our listening, either directly, or by interacting with the soundwaves in the room (as Kalman suggests).There is a much more mundane explanation as to why these supertweeters change the sound of a system. you are basically adding components and complexity to the existing speaker crossover when you put a supertweeter in a circuit. You typically attach a supertweeter to either the amps output or to the main speakers terminals. When you add another speaker to an amp, the amp sees a different load. In the most basic sense it usually lowers the impedance of the speaker load the amplifier sees. That's usually audible. You are also changing the resistance, damping etc. the amp sees. The main speakers crossover will also be similarly effected by the load of the supertweeter, the damping and backwave it creates etc.
All of the supertweeters I know connect with this method. It's also the explanation of why the Golden Sound supertweeters make an audible difference.
If you really want to test the pure effect of a supertweeter and not the R-C effect Al explains, you need to set up the supertweeter on it's own amplifier so you are listening to just the effect of the supertweeter and not it's electrical effect on your current system. I'd love to hear a setup like this, I bet it would be very educational.
