This supposedly stabilizes the windsheet, so that =   it maybe better for gedekts to be lined up with the pipefronts facing immediately the backs of the frontpipes. If I remember it right, the opposite is true with string pipes. The speech of string pipes is = supposedly sensitive to the amount of surrounding open space. For most pipes, he recommended space in front of the pipes at least double the area of the cross section of the pipes. Then there's the issue of tuning problems if there's no adequate space between two adjacent pipes which are only semitones apart. I've seen recently built organs where this space recommendation is not evident. Is there a more recent consensus/recommendation on pipe spacing.
