When I compare a low Bb to a low A, I find that I like the aesthetics far more on the Low Bb horn. It looks more like a saxophone and less like a brass tube. Honestly, the impression seems to come from examining the bell, which is lower and has a bigger "throat" where it begins to flare (in my ability to estimate). The longer flared section acts as something of a High-pass filter if my physics is correct, and it gives the bell notes a similar tone to the higher notes on the sax.
On a low A, the bell is there, but the flare seems to be no larger than on the low Bb. I suspect in my mind that it should be considerably larger since the tube itself has to get larger just for that little half step.
Why doesn't someone try to recapture the low Bb look in a low A? it would involve a little rethink on the keys, since a bell key would be relocated to the body tube, and the body tube would gain 4 inches or so in length, but the reward could be huge. First, you would lose that "tube look" and regain the sax profile. Also, we could rethink the bell diameter, length and flare to be designed for a Low A instead of the low Bb. Finally, it might recapture some of that sound that low Bb bari players want that make them refuse the low A.
I can't be the first person to think about this, but it isn't easy to pick out a good search parameter for this either. Why isn't someone building this? It isn't so radical, is it?
