Afforable Speakers (Meet Ultrasonic 20kHz Requirements)

[Tigurinn]

Thanks guys, and yes - it probably is mono since the seller couldn't tell, as it isn't stated on the packing of the product (manufacturers who produce units that only play mono are just as silly as those who would only produce televisions that only display black and white).

And the frequency response for the unit was too suspicious.

UPDATE: Weeeeelllll, I just got quite a bit of shock. THE SPEAKER ON THE IPHONE IS F###ING MONO !!!!!!

So I'm pretty pissed off at Apple at the moment (no f###ing wonder I never got really anywhere with subliminal products); can anyone guide me to a stereo speaker that I can have covertly in my shirt pocket, so I can further test Poetry of the Silent Eros ???
