The sweet spot/toe in variable seems to lend itself to almost as much debate; do you adjust sweetness to a single location, or do you compromise to expand the geography? Another personal preference no doubt.
Right. Most speakers will image best pointed almost straight at you. But imaging isn't everything, there's balance and space and width, and no right answers only your personal preference.
My personal preference is of course amazingly fantastic, but even I cannot tell you how to achieve it via remote control. However wonderfully worded the advice may be it all comes down to you.
