I am pretty sure that the PAS cannot be compared to an organ pipe. Each pipe is hollow and tuned to a single pitch. The PAS column is full of speaker hardware and does not resonate at any particular frequency as an organ pipe would do.

The electronic pipes you mention - made by Allen Organ - played only one note each. They were tuned to resonate like regular pipes. The speaker in each one enabled single pipes to produce flue, trumpet, reed and other voices, so only one rank would be needed.

Big ol' caveat here...I am not an expert on organs nor do I own a PAS. Y'all please let me know if I am off base here.
