"Other than that, there's the length of the tubing of the trumpet or
trombone and most significantly, the bore size.  Trumpets have a bore size
of around .450 to .472 and typically around .459 or so.  Bass trumpets have
a bore size of around .486 which is invading on the bore size of a
trombone...."

So you are saying trombones are bigger bores?
