Here are the specifications that are purportedly provided by the manufacturers on their largest BBb tubas:rodgeman wrote:Isn't the Miraphone Siegfried prototype going to be this size?

The only specification shown on the Rudolf Meinl website for the "6/4" BBb tuba is the bell diameter: 56 cm/22".
I would imagine that Herr Meinl would supply the other specifications if an inquiry were addressed to him directly. Also, there are at least two 6/4 Rudy Meinl BBb tuba owners who read TubeNet.
Unfortunately, there are no specifications shown on the 6/4 Meister Walter Nirschl BBb Kaiser tuba. The only spec provided for the Boehm & Meinl Model 555 6/4 BBb is the bell diameter: 48cm/18.9"
The information on the Hirsbrunner is listed for comparison only because that horn is probably no longer built.
According to correspondence with one of the engineers assigned to the Siegfried project, the estimated release date is late autumn 2011.Has anyone heard if it is going to hit production soon? I checked a couple of months ago with Miraphone and they did not have a timeline.
FWIW, the Siegfried is the only tuba listed above that I have played for more than 10 minutes (I played a 6/4 Rudi for that amount of time--much more time would be needed to get comfortable with its demand for slow, thick air). The Siegfried was very easy to play. I'd certainly like the opportunity to play the other models before I would buy one of these 6/4 BBb tubas.
The differences between the Cerveny 601, 701, and 696 are not clear, except that the 601 and 701 are heavier than the 696. Perhaps the diameter of the throats differ, but that is not stated in any manufacturer's specs (where on the throat would one measure for uniformity--just before the bell flare?).
