After all the discussion lately, I thought this might help. Call it the "Model 950 bass management cheat sheet."

6-channel analog input

• bass management off: full-range speakers receive full-range signal, subwoofer receives LFE signal plus information below 80Hz from the other five full-range speakers ("double bass" condition); subwoofer also has a filter that discards material above 120Hz on the LFE input signal (material that subs typically can't reproduce well)
• bass management on: full-range speakers receive all information above 80Hz, subwoofer receives LFE signal plus information below 80Hz from other five full-range speakers; subwoofer also has a filter that discards material above 120Hz on the LFE input signal (material that subs typically can't reproduce well)

Stereo Bypass Mode

• Mains set to LARGE: Left and right channels receive full-range signal with no processing, subwoofer is off
• Mains set to SMALL: Left and right channels receive full-range signal with no processing, subwoofer receives information below specified crossover from left and right channels ("double bass" condition)

Digital bass management

• Applies to all digital inputs and all stereo analog signals that do not use the "stereo bypass" mode
• Any speakers set to large will receive full-range signal with no data sent to the subwoofer (crossover setting is ignored)
• Any speakers set to small will receive all information above the specified crossover and nothing below the crossover; data below the crossover is sent to the subwoofer
• subwoofer will receive the LFE channel of multi-channel soundtracks as well as any re-directed bass from small speakers
• If there is not a subwoofer (sub turned off in the menu) and the mains are set to "LARGE," then information redirected from small speakers will be sent to the mains and the LFE channel of 5.1 soundtracks will also be sent to the mains

It's be a rather hectic day, so there may be errors in there, but I think that's a fairly complete capsule of the 950's bass management modes...
