-wellll... to be proper, some amount of the energy is absorbed by that
microphonic element at the end, or you wouldn't get any signal out, and the
rest is reflected.. if you had a perfect spring and a perfect microphone,
you could transfer ALL of the energy into the microphone and have NO
reflections, but of course this wouldn't make a very good reverb..

just being a stickler for science :]
