Question concerning horn path length and fc

Once you have gone below fc, should it still be assumed that the sound source is the horn mouth? For instance, when below fc, should you figure on 6dB drops per distance doubled from the horn mouth, or horn mouth plus horn path length?
Thanks,

The mouth is always the source.
