Speakers positionning

I just try a new toe-in for my speakers, and it worth the move.  Instead of crossing the focus behind my head ( at position seat), now it cross in front of me at 2 feet.  The highs are well defined and present  with well blend music and no more edgy treble at "forté" passage...  But it depends of your room and speakers...  You can read more about here:
Drivers will have an equal dispersion pattern laterally, i.e. to each side of the driver, so in terms of brightness, etc., a speaker oriented to cross 2' in front of your head should sound much the same as a speaker oriented crossing 2' behind your head.  But with most, not all, speakers, this will affect the soundstage.  Definitely worth experimenting, as each speaker, each room, and each interaction between the two, is different.
Going off-axis often reduces any top octave or higher ringing. An especially good idea for a lot of (but not all) metal tweeters, including some Be's.

Crossing in front of your head you reduce side wall reflections, so it makes sense to me, overall.

It's certainly a better idea to try first than new cables or amps. :)

I’ve said it before and I’ll say it again, the best soundstage along with everything else can ONLY be achieved using a foolproof method like the speaker placement track on the XLO Test CD or similar test CD. The better the room is treated for acoustic anomolies the bettercsuccess you will have with this method. You will find that speakers generally should be placed CLOSER together than people assume AND toe-in is a make do substitute for not having the correct speaker locations and or room acoustics treatments. Trying to find the IDEAL SPEAKER LOCATIONS by trial and error is like trying to solve x simultaneous equations in x + N unknowns. You will inevitably wind up with local maximums but not (rpt not) the real maximums.

Do you think it makes sense to design speakers that deliberately minimize room-interaction acoustic anomalies?   Or do "foolproof" setup methods take the speaker's characteristics out of the equation?
