@Kehaulani What do you mean, "take more air"? Technically, yes, a larger bore is a larger diameter, which creates a larger volume of air.
The volume of air in a horn is static. Large bore, medium bore or small bore. We do not replace that air when we blow into the mouthpiece, but are vibrating the air that is already there. So it takes no increase in air (more air) in a large bore horn if the efficiency in the vibratory freedom of that horn moves the sound wave through the medium filling the horn.
I'll disagree a bit. True, the air is already in the horn, but the act of blowing to induce lip vibration does move air through the instrument.
Watch the video of blowing smoke through the horn. It moves very slowly. It's the vibratory wave that transmits rapidly.
