    With all other design parameters held constant, as you increase
    the bore size the higher overtones will be
    weaker.

    If you don't believe it, well too bad.
    Any one (like me) that has replaced a
    stock tuning slide with a large bore version
    would have heard the difference.

    OK, Nordlands, where do you get Carol cornets? Wanna sell the other one?

    NOTHING - if everything else is equal.

    You are hereby officially invited to come to my house and try the two cornets
    I have shown and then tell me the NOTHING difference any time, except when I am on vacation.

    I will get and bring both horns to the same place at the same time and temperature.

    There is a difference as I explained in a previous post.

    Wouldn't the bore size primarily effect the dimension of the valve tubing?

    I mean if the lead pipe were made shorter for a smaller bore. The tubing in the valve section would be narrower.

    Seems like smaller valve tubing tubing would be especially noticeable playing a low F# for example.

    So if you play the horn open valved, then their really shouldn't be much difference between the horns of different bore.

    IMO A larger bore would mean that less of the length of the horn is spent in the valve section, since the volume of the air in the valve section would be the same for shorter lengths, therefore the intonation may be better for those horns, since less of the taper would be interrupted.

    Taken from the thread "How does a trumpet work?"

    The bore size itself increases the total volume of air in the horn and that acts like a low pass filter, damping high frequencies.
    All other factors being the same, this would lead to a slightly darker tone

    There are risks associated with being an inflexible know it all.
