Given that the bore of a typical orchestral C trumpet is around 0.462 inches, the bore of a CC tuba four times the size should be about 1.85 inches. If one wants the tone of a tuba to be comparable to a trumpet two octaves lower the tuba must be four times as large in all physical dimensions. One might be able to cheat on the thickness of the tubing to keep the tuba from weighing 64 times the weight of a C trumpet but the bore must be 4 times that of a trumpet. Otherwise, the tone will almost nothing but high harmonics making it sound like a contrabass harmonica rather than a contrabass trumpet. It is most odd that manufacturers and players don't seem to understand even the simplest principles of similitude!
