When discussing scoops with our mutual friend Blomman, he says the Fs should be high and the Q not too low. I agree. Low Q is good for increased bandwidth upwards, but in a scoop you want the driver to do the mid duty through direct radiation.
High fs is because it is only the horn loading the driver. With a low fs driver the cone will travel uncontrolled below the horn fs.
Based on this logic I would rank the drivers this way:
