That is exactly what is happening. This is what I'm doing when this happens. Using the Chesky disk, DD setup, track 23 - 60Hz phase test which is a test for setting the phase between the mains and sub. My mains are biamplified and I have the lower bass section of the mains turned off so the only thing reproducing the 60Hz tone is the sub. The sub is being fed it's signal with the LFE output from the 950. I believe by just having the sub reproducing the 60Hz, phase doesn't matter since the sub is acting alone.

DVD playing track 23 repeating, no bass management in the player.

950 set to optiacal input, volume set so RS meter reads 80dB, all speakers set to LARGE, sub ON, crossovers set at 150Hz.

While playing the tone I went to the speaker setup in the 950 and took these readings from the RS meter while lowering the crossover setting for the front speakers:

Crossover setting -------RS meter (dB)
150Hz -------------------80
120Hz -------------------80
100Hz -------------------79
80Hz -------------------78
60Hz -------------------75
40Hz -------------------65

My conclusion is that you do get summed bass to the sub in digital mode and it is crossed over at the front speaker setting. Another odd thing is if you turn the sub setting to OFF it forces the the bass signal to the surrounds as well as the fronts but not the center. It only forces to the surrounds if they are set to large and none of the crossover points change the output. Strange?
