I've got some notes on bass management in my 950 review to help explain the various options, but Mr Garcia was referring to the bass management on the 5.1 analog input. That input has a toggle switch for bass management "on" or "off." When off, the five speakers get the full range of information from the source; the sub gets the LFE data, plus a copy of all data below 80Hz on all five full-range channels. When on, the five speakers get their full signals minus everything below 80Hz; that information below 80Hz continues to be re-directed to the subwoofer along with the LFE signal. If you have speakers that aren't capable of full-range operation (if their -3dB point is 60Hz, for example -- a pretty reasonable number for a surround speaker) and you send a 22Hz signal to that speaker at very high volume, you might be able to damage the speaker. I'm not sure just how feasible it really is -- others around here could shed some light on that.
