A double-mouthed half-covered stop of 8' or 4' pitch, essentially a cross between the Doppelflöte and the Rohrflöte. It is most commonly made of wood. When made of metal, Audsley recommends a one-fifth mouth, arched upper lip, and a wooden stopper perforated with a vertical hole. The 8' octave is often of stopped pipes with single mouths.
Audsley describes its tone as �brighter, lighter, and more open� than the Doppelflöte. Irwin describes it thus:
The double mouths of the Doppelflöte emit a strong fundamental and a few of the lower-pitched odd-numbered harmonics. The rohr of the Rohrflöte gives a soft overlay of even-numbered harmonics, making this timbre just a little �open�. This large-scale wooden rank is really a stopped Flute in tone. However, it approaches some distinction in tonality by its liquid and pervading voice, which is moderately loud.
