He is still very adamant about always using Small settings.
Keith made a good point about optimizing speaker positioning, as well, but even that is just a general guideline and not an absolute. I think we all have to pick and choose what recommendations we are going to follow, and where we are going to experiment and then use our own judgment. And frankly, I think that includes not only the advice we can receive on this thread, but Chris' advice, as well. Among the variables which I personally think are important in deciding where to keep your crossovers are: how much you use your system for music, and whether you can hear differences in the sound of your satellite speakers and your sub(s); and what volumes you like to listen to. As Keith was pointing out, it takes a lot of power, and very efficient speakers, to approach Reference volumes in even a fair size room. So, the closer you want to get to Reference, the more important it probably is to have very capable subs to which you can offload bass below about 80hz. On the other hand, if most of your listening is done at -25 to -20, the easier it is to feel comfortable about using lower crossovers.
Almost anything we can say about most of this is a generalization. Keith has been at the forefront of establishing guidelines (the FAQ) which have helped innumerable Audyssey users, including myself, get started. But once we start to understand the basic principles involved, then if we want to go beyond the guidelines and experiment to discover what we really like, then there certainly is no harm in that.
I agree with every thing you said. I just find it ironic that the "official Audyssey thread and faq" does not even mention what the creators of the software actually recommend.
