[QUOTE="Buck, post: 8869835, member: 591582"] [MEDIA=youtube]XpNbyfxxkWE[/MEDIA] Distance is frequency, different distances change resonance due to wave speed and length. This is just a great visualization. When he moves the reflector and the levitation stops, that seems to me like playing a note, then suddenly making an enclosure out of resonance with the speaker frequency, so stored energy resonance is quickly lost. That's why there's different lengths to ports in sound; you lose so much energy out of resonance. [/QUOTE]
