Some companies will use Fo instead of Fs when listing their T/S parameters. They are (meant to be) the same thing. Some companies call Fo the "lowest resonant frequency".... LOL, but it is the same damn thing... Europeans use Fo more than Americans. The Aura NRT-18s I bought a few years ago listed the Fs as Fo on the spec sheet....
