Chris is the chief technical officer of Audyssey, Dave is owner/designer of Ascend speakers, Marc is an Emmy award winning sound mixer, Roger is an EE and used to be director of technology strategy at Dolby. They're hardly "non-qualified, anonymous posters".
There are others, like Earl Geddes and Brian Ding, who go through significant efforts to get a smooth and seamless blend between speakers and subs. In fact, Brian has 3 pages at his Rythmik site dedicated to using phase and delay to get a better integration: http://www.rythmikaudio.com/phase1.html
A bookshelf speaker with a 4" mid-driver will "blend" just fine with a 18" subwoofer.
Then we have different ideas of "fine".
