Sorry, no, there's nothing about harmonics in the BASIC Stamp Manual.
I'll have another post for you in a bit. The short answer is that speakers are always like filters (woofer, midrange and tweeter) all filter for a particular sound frequency. So it would be rather difficult to broadcast the harmonic with a speaker (unless you are using an ultrasonic speaker). Infrared broadcasts it, and so will a wire.
