The point about the Ripieno is that it's a buildup of octaves and fifths. So 8ft and 4ft Principal, then Nazard, Fifteenth, Larigot, 1ft, fifth above that and the octave above that. Of course they break back to the lower octaves at the upper end of the keyboards.
But perhaps people are familiar with the mock 32ft effect by playing fifths on the pedalboard. A fifth produces a beat note an octave below the lower note of the fifth. So as one starts to add octaves and fifths their beats add notes below them, and if these beats are strong enough, they will add octaves lower still. It's for this reason that the Ripieno adds gravitas whilst apparently going higher.
