Fundamental Frequency
Yes, I agree with you that you can not go slower than the fundamental frequency. However the controller let's you go faster than the fundamental and slower than the fundamental, at least for my tank. So it allows you to control the sway frequency and amplitude within special constraints. The amplitude can be controlled by slightly off tuning from the fundamental or 2X the fundamental. When you do this then you are causing some destructive as well as constructive interference between the direct and reflecting wave and thus you get a smaller wave.
