Imaging
"Although the front and rear speakers create the soundstage, it should seem to come from in front of you, filling the space from left to center to right."
You can get this effect by having all the speakers the same, and polyfiling the front speakers just a little bit.
"The speakers themselves should seem to disappear, replaced instead by a spatial arrangement of music sources, or soundstage."
You also get this effect by having the front and rear speakers the same size and manufacturer. Cutting the natural sound from the rear speakers, using 6.5" speakers in the soundstage, defeats this purpose. Having all the speakers the same, helps accentuate this idea.
There are other statements in the above article that supports 5.25" speakers all around for the best soundstage and imaging experience.
