So you put a 200 kHz tone and a 201 kHz tone into you tweeter and you claim you can hear something...?(!) First of all, I would guess that 200/201 kHz tones will bounce right out of the immitance presented by the tweeters and (virtually) NONE of that energy will get converted to acoustic energy. Secondly, the distortion products generated by the ELECTRONICS will probably generate the 1kHz tone for you, even if your ear doesn't. This assumes that the 200/201 kHz makes it past the input stage of the power amp in the first place. To test your hypothesis you need TWO separate channels, and probably something other than hi-fi tweeters as transducers. Put 200 kHz into transducer 1, and 201 kHz into transducer 2; let the acoustic medium - air - be the combining device, and see if you can hear a 1 kHz tone... Let us know what you find out. keith ericson at teklabs
