Although slightly off topic, it should be noted that Bach was more directly involved in the work of Zacharias Hildebrandt than with Gottfried Silbermann. Hildebrandt's masterwork, the 3-manual organ of St. Wenceslaus in Naumburg, probably had significant design input from Bach. The organ has one 32' stop, a Posaune, and was intended (by Bach?) to have a second 32', an Untersatz, for which a draw-stop knob was installed at the keyboard. Unfortunately, the casework for the organ, which was retained from an earlier instrument, turned out to be too small to accommodate the large flue stop, which ended up not being built.
But yes, indeed, Bach loved his "Gravität" in the sound of the organ. Another example of this is the Herbst organ in Lahm, Germany, where a nephew of J S was organist. Again, it is likely that J S had input into the design of the organ, which is two manuals and 29 stops, one of which is a pedal 32' Posaune!
