So are you saying with that (or at least the idea of it) is that, the heavier trumpet's intended design whether it achieves it efficiently or not is supposed to get all the wave lengths that go from air-lips vibrating through the mouthpiece out the horn rather than lost/scattered through the movement of the horn itself? So rather than sounding more dead, it should be 'more powerful' as more of the sound actually comes out together rather than lost/scattered? - What i mean by that is if I visualize a wave length, or many of them... the intended use of a heavier horn is to keep those lengths 'together' coming out the way they went in from the mouthpiece section rather than coming out the bell in many/which directions? So how would that then be different from a more 'focused' (mono) sounding trumpet and the ones that sound more 'stereo' like where the sound is everywhere? Maybe I confused 2 aspects here.
