One more 'thought,' or perhaps it should be a 'non-thought' thought.
Like such things as technique, intonation, phrasing, type of tone, sound concept etc, etc, etc, 'projection' is best when it is on 'auto pilot.' In a perfect world, one's concept and approach to projection, whatever that might be, is an aquired skill. It does take sufficient practice to be able to pull it off 'without' thinking about it.
Personally, I particularly enjoy getting a chance to practice 'projection' in a large room. Learning how to send the sound from the mp, out the horn and to a certain 'other' place takes a 'bit of getting use to.' At this point in life, I believe it is something I tend to do automatically. It pretty much only takes one healthy note to figure out the feedback from the room. But the skill to keep automatically 'pumping' those notes is 'acquired.'
I also concur that projection is more about the player than the horn.
If you stop to think about it, there is a term that perhaps is something more inherent to the instrument, and that is "presence." How does the 'combination' of tuba and its mp actually respond, type of tone, and how does that sound 'hold together' when pushed to its limits in a high performance situation such as in a world class major orchestra where all eyes and ears are on a certain player, performing certain repertory, that has certain expectations of how 'grand and glorious' it should be rendered. Subtle differences can make or break the experience.
