That's because of the LP or HP behaviour at the bottom/top end of the
frequency range. It depends upon the number of stages used and the
positive/negative polarizer setting.

For details look at the frequency responce pictures on our web site (the
first black/green ones on the A-101-3 info page). If an even number of
stages (12, 10, 8, ...) is used the behaviour (LP or HP) is the same at the
bottom/top end of the frequency range. If an odd number of stages (11, 9, 7,
...) is used the behaviour (LP or HP) is different for the bottom and top
end of the frequency range.
