Most interesting. The powerpoints and powerplanes have the same driver set up.
Perhaps there is some boundary interaction with their placement, or perhaps off axis response differs significantly from on axis -- but that wouldn't usually be a roll off on the bottom end, but rather the top.
Have you ever had a measurement done or done a measurement outside of the Audyssey context? I've now got three data points (professional calibrator, my own use of REW, and Audyssey xt32) all saying the powerplanes roll off somewhere between 110 and 130hz.
