If i remember correctly it's for the lower registers (but i could be wrong)
Raimus/Ramius (my most humble apologies) is the chap to ask.
For what it's worth i have invested alot of time into this sort of thing (meter's, sub test cd's etc) trying to set these thing's up by exact spl readings etc is just really hard and not always satisfying experimentation. You've just got to go with your ears on this one, Example, the meter seem's to read "strangely" when trying to set correct phase alignment which "seems" obvious by ear. Odd!
