Audyssey recommends 40hz as the determination if a speaker should be small or large, this is the criteria then used by the receiver manufacturers (Denon, NAD, Onkyo, etc.) which then set the speakers size setting during the setup. This is followed by Audyssey setting the appropriate crossover for each speaker. Marantz is the only company that still has not come onboard like the other Audyssey enabled products, and they still use 80hz for the small/large determination. In these cases you will have to manually change the speakers setting to small.

Dave, below is a response Chris from Audyssey gave another person about lowering the crossover point Audyssey finds.

"If you lower the crossover then you won't be getting any MultEQ correction below the rolloff point that was found. MultEQ stops correcting below that point to avoid overboosting below the –3 dB point of the speaker (as it measures in your room)."
