If (big if!) you're the only one listening, not only is there no point in measuring other seats, but you'll get sub
-optimal filters for your
seat. Dunno if Audyssey will keep multiple cals, but if it does, create one with measurements only at and near your single seat, and another for the multiple seats used when friends or family join you. Try them both and see which you prefer in your
Slightly OT, my Trinnov will show the correction for all measured positions, allowing me to see which are sufficiently different that I may choose to discard them when creating the filters. To make a long story short, after many listening trials and in my almost-always single seat listening room, I use only one measurement position. YMMV.
Right, we can over think this. I also think we also tend to expect more precision from Audyssey or other EQ than is practically possible given the extreme complexity of sound patterns in the room. The continuously variable nature of room acoustics which we measure samples of only at discrete points still requires some spatial averaging to be more accurate, given that we turn our heads, lean slightly or slouch sometimes while listening, at least I do.
It may be a compromise, but I think a two point measurement, one for each ear head in a vice-style, would be less useful and accurate than using more points. Chris has advocated doing measurements 2 feet in front of the listening positions, as well as the main listening positions, as well. Others have advocated adding some positions at a foot or so above the listening positions, especially if using dipolar speakers with limited vertical dispersion. I have not tried that yet, but I will. Personally, I have a 3 seat sofa, and I measure all around it, over the backs, fronts and side arms, plus I add several center weighted positions about a foot apart over the center of the center cushion. I am quite pleased with the sound at the sweet spot, but also everywhere else on the sofa.
I did the calibration for a good friend who listens by himself from only one chair. I did 8 points, just all around the chair. I must say it sounded pretty good there, but it also sounded better elsewhere in the room, but there was no point I thought in calibrating anywhere else. Life is too short to try every possibility.
But, the bottom line is that Audyssey is not meant to be or is it capable of providing perfect sound anywhere or everywhere. Passive treatments or anything else cannot do that either. It can only make the sound in the room better by partially removing many common room and speaker induced faults in the horrendously complex sound fields in the room near the listening point or points. To me it does that extremely well, and that is all I expect from it. If I can tweak it to do a little better, I am happy to try that, too.Edited by fitzcaraldo215 - 2/27/13 at 9:27am
