The sound is not "wasted" in any way, in fact a tuba's sound is not a very directional so anything coming off of the instrument's body is radiating "practically" the same as what's coming out of the bell except the player can hear it better. Isn't that fairly important
I'm not sure that I agree with that completely, Doug. For example, consider a tuning slide branch that's badly under-braced. It vibrates like heck, but the surface area of the branch isn't sufficient to be a good radiator at tuba frequencies. Even if it were, consider that the player is holding the horn, thereby damping some of the vibration not coming out of the bell.
Or so it seems.
Maybe the answer to my question really is "Brace a tuba just enough, but not too much."
