(Technically, LFE extends to 120Hz, but most producers roll of the LFE bass above 80Hz, which is one reason THX chose it as their standard. 80Hz has since become the de facto standard for the industry in general.) LFE is not transferred to the main speakers when a sub is available, so lowering the crossover means only the portion of LFE below the crossover point is reproduced.
This effect is not always apparent, though, because it is common practice to include the same lows in the front channels (sometimes more), which masks the effect. However, the main channel lows are meant to be mixed with the LFE, and if the sub is not doing its share, they will lack the punch the producer intended.
Also, turn OFF the THX speaker settings in MCACC unless you have THX certified speakers. These settings affect the crossover slope, as they assume speaker rolloff patterns that non-THX speakers are unlikely to duplicate.
I think technically you're right about that, but the large speakers should get full range. To clarify, you are referring to the smalls?
What I've noticed is, for movies, 80hz sounds better - as they purposely only create range specific content for the particular speakers.
However for traditional stereo CD's and such that you're are running in either Auto, or one of the DB Music posts, the surrounds sound much better at 50hz. I have a pool table in the back of my theater area, so you become closer to the rear surrounds and at 80hz, the sound out of those speakers becomes clipped for lack of better words. Essentially it sounds like a loose speaker wire as the music that's clipping the crossover is being omitted - rather abruptly. At 50hz, I don't notice it near as much. Naturally, when I go all large, it doesn' happen at all. Too bad you cannot change speaker sizes and cross-vers with the MCACC presets. That would be the hot ticket. Any friendly hackers around?
