Maybe a bit more background will clear things up ... I use the system for about 80 percent 2-channel stereo listening. So, the main goal is to augument the Maggies below their 40 cutoff point. The full-range signal from the high side of the 80.3 will feed the maggies. The low side will feed the subs with a lpf of 40 or 45 ( I'm not sure exactly where the maggies start to roll-off... is the 40 a 3db down point for the Maggies ? ) . This would provide a 20hz to top-end-of-the-Maggies for Audyssey to work with on the front channel. The LFE channel would also go through the mains with the bulk of handled by the subs, and the higher parts of the LFE handled by the Maggies ( which should do a better job the subs in the higher Hz portions of the LFE channel).
Don - it seems like you know what you are doing and have the bases covered for that rather unconventional setup you describe. Why not just do it and see how it sounds to you? And, of course, please report back and tell us here in the thread.
Another of the reasons I'm thinking about this arrangement is to aid in the localization of the lows in true stereo recordings. ( no need to rant about no localization of lows, The "impact" from the bass on the right is quite different from the drums on the left ) .
Not to start a whole new discussion about the merits, or otherwise, of 'stereo bass', but isn't it just the harmonics of the bass and the drums that you are hearing - or the easily localisable transient 'leading edges' from the right and the left, thus creating the illusion that all of the bass emanates from those locations, whereas in reality, the deep bass is non-localisable mono? Please don't feel the need to defend your POV on this as I am agnostic on the virtues or otherwise of 'stereo bass' and just toss this thought in, that's all.
In addition, there are times when I am not always convinced that Audyssey treatment sounds quite right on some stereo recordings. It "seems" that maybe some phase-shifts might be occuring that throw off the sound stage, and in those cases using "direct" just sounds "more right" to me.
It has often come up in the Official Audyssey Thread that various people do believe that they prefer a 'pure' sound untouched by Audyssey for music, while they turn Audyssey on for movies. My personal view on it is that I don't quite get it. The system could care less what it is playing and has no 'idea' that it's playing a movie soundtrack or a rock or classical concert, so I’d have thought that room correction was always going to be important, regardless of the source. The room is the biggest influence on the sound after all. HST, I am a die-hard stereo fan and have a totally separate system from my HT, in another room, with a lovely big Class A amp/room heater and two fairly large "full range" tower speakers. That room has no treatments, other than normal domestic stuff such as carpets, large sofas (couches) and curtains (drapes). And of course it has no Audyssey or other form of electronic EQ. Yet to my ears it sounds wonderful. But the reason I believe it does is that, over the many years the system has been with me, I have learned to 'listen through' the room and subconsciously 'adjust' for the deficiencies of the room and the system. As ever, YMMV and what sounds good to you is what matters.
It raises an age old question: do you prefer the naked truth from your system which mercilessly reveals bad sources for what they are, or do you prefer a system that makes most music sound rather good and enjoyable? It's all about preference and there is no right and wrong to it. Personally, I used to prefer the 'naked truth' but these days, with music, I prefer to have an enjoyable experience that sounds great to my ears, even if it is less than accurate compared with what it might be, or with real life. I listen mainly to small jazz combos, Duke Ellington, Ella Fitzgerald and the like and have spent more hours than I care to recall in live venues listening to the 'real thing' (including those two famous names and many more - I am revealing my old fart status here :)) so I think I know what my sort of music sounds like - and my music system plays it well, to my ears, and always enjoyably.
Anyway, these are just some of my thoughts on how I can provide the best comprise to provide the sound I'm looking for under many various source conditions.
Good to hear them. Many people who have graduated from consumer Audyssey to Audyssey Pro say that Pro makes Audyssey work wonderfully with music sources, so that might be something to consider if you haven’t already done so. I also think that XT32 works well with music and movies - what flavour of Audyssey do you have?
