orphean for 220hz high-pass not too small ? (Orphean)

i am doing my projects, one at the time. When the ongoing one is finished, i start with the horns. Next will be a mid-bass horn, and a midrange horn. I do not have yet practical experience, i am still at the very beginning, so i rely on others knowledge. Regarding the horn size, i would like to mention also a other expert, witch does say practicly the same thing as JMLC, but in other words :

Make an experiment, and I will simplify the case quite assertively. Take a typical compression driver, cross it at 800Hz, second order and load it into a proper contemporary horn (Tratrix or JMLC) of 300Hz. Listen that horn, you will get some sort of sound that let accept as OK Sound. Now begin to very slow lower the crossover point and keep listening the channel. While you lowering the crossover point, somewhere around 550Hz (I took this number purely arbitrarily as it would depends from VERY MANY circumstances) the horn will begin to demonstrate what I call “choked sound”. The “choked sound” is HOW HORNS SOUND IN 99% OF ALL HORN INSTALLATIONS OUT THERE – people just too **** to deal with it. The “choked sound” is the satiation when Sound produced by a driver can’t be “processed” by horn. In this “choked mode” a horn produces the “sonic boom” that was made by the horn’s bell and that “sonic boom” screw up the enter band-pass of the channel - the game is over. Increasing of the crossover point for ¼ octave (for instance) will fix the situation - so we have approximately one octave between horn’s rate and mix crossover point…


what negative consequences do you think would imply following this rool ?
