a larger bore will generate a larger sound but it will physicaly demand
more air to get this larger sound so it takes a few weeks to get used to
filling up the horn. but once you're used to it the larger bore really
is better. a bore size of .750 to about .825 is the largest you will find
in pistons but rotory valves can go up to about .920. the larger the bore
the more air the horn will take to produce a large sound.
