thank you sir
The brace removed lets the bell vibrate more freely, which will give more response to you as a player, but at the sacrifice of a little projection to the audience. The vibration gets lost at the player's point rather than being sent out to the audience.
I wonder if that's why the shaped the Commitees bell the way they did
The shape of the Committee bell emphasizes spread over projection. Strong players can project on a Committee, just as strong players can on nearly any trumpet. I choose not to use my Committee for loud gigs, because I have more efficient tools for those settings.
The horn is the sum of its parts. The bell shape alone says nothing. The Committee bell is matched to the rest of its concept.
Some braces are to damp, others transmit vibrations to another part of the horn. Leveraging that difference has better odds than the lottery.
The reverse lead pipe set up is cheaper to manufacture.
Seriously, I didn't know that. It doesn't reflect that in the purchase price of most horns though.
I'm a tuba player who doubles on trumpet for fun. When we have to drop down into our petal tone range, we start using our extra 4th and 5th valves. When we do this we start to experience large amounts of resistance or what feel like back pressure to the air flow. This would be in reverse of what Bach is representing in their ad copy. Also for a tuba player to feel this resistance we are adding 18" or more of length to the horn. I doubt that the slight change in length of the lead pipe found in a reversed lead pipe would cause a noticeable change in feel.
Sound does not travel with the air flow through the horn. I watched a smoker who played tuba demonstrate this by playing while exhaling his smoke through the horn. It took several minutes for the smoke to start exiting the horn after he started playing. Air flow is used in the production of our buzz only. The resistance felt is from our need to make the volume of air in the horn move so we can produce our buzz.
