It is much more difficult to filter low frequencies than high. With the components available these days, there is no justification (other than ignorance?) to using a low frequency signal.

Sorry I have no source of accurate data. Is suspect you are going to just have to do as the TEC manufacturer, and just say, 'Don't do it.'
