as i've mentioned before, i'm using a bass management system that i devised a few months ago and i don't have the ambition to reconnect my setup the conventional way. however, i can verify the following:

dts-es discs: pearl harbor, gladiator and lord of the rings ALL have LFE content. with speakers all set to 'large', there is no redirected bass (as it should be).

with my system, the speaker config menu doesn't affect the LFE signal whatsoever, so i can't verify whether or not the LFE gets lost or otherwise redirected when front speakers are set to 'large' in the conventional system.

some dvd-a discs have no LFE info (this amounts to false labeling of the discs as being 5.1 when, in fact, they are 5.0... thank you, mr. elen).

massi2u: where did you buy the lord of the rings disc?

i did notice one curious thing in my tests that i didn't know before. i tested some dts-cd discs also. i tried to play them through the 6 ch bypass and got a loud hiss instead of music. i wasn't aware that dts-cd isn't output through the player's analog outs.

i'm also curious to know why you (massi2u) get nothing in your sub with fronts set to 'large'. unless ALL of your satellites are also set to 'large', you should at least be hearing some redirected bass from them in your sub.

anyway, if anyone else tests this situation out, make sure ALL satellites are set to 'large' so only LFE should be in the sub.

massi2u: when setting main satellites to 'small', i'm guessing that you have vented front speakers. depending on which ones, the 12db/octave high pass filter that's applied when setting them to 'small' alters the low freq slope to 36 db/octave and may cause a bump in response at the corner frequency (and it will be slightly different for each HP point selected). this makes for a bad crossover with a sub LP slope of 24db/octave (the standard BM LP slope), resulting in a hole and a bump at crossover. also, as KCB has said before, there may be phase issues added to this problem. finally, your subwoofer may simply not be doing a good job, making it impossible to reintegrate the redirected bass.

you can try setting your sub's LP point at 10 hz higher than the HP you select for the mains and experiment with the phase reverse switch and/or control. if you do, give it a couple of days so your ears can acclimate.

this isn't such a big deal in 2 ch music, but a sub and the same high pass for all speakers set to 'small' is definitely better for multi-channel formats.
