It is depends what kind horn it is. For LF horn the resonance should not be “an octave lower then lowest frequency you can realistically get from the horn”. In fact the common way is to much the assembly resonance to the horn cut off by squashing the back chamber. Theoretically it cancels out the throat reactance in the horns with the small throats but in practice only God knows how those upperbass horn would sound when you are done. For the HF horn it is kind of correct: people hide the primary resonance behind the horn rate but I do not know the rules how far. In realty no one manage the compression drivers resonance intelligently but people use whatever compression garbage was already accidentally made for us. I was playing with managing the Fs of compression drivers, got very inconclusive and uninterruptible results and … abandon to think about it. In compression drive the secondary resonances and the resonances due to the crappy driver design are more effective then the Fs.
