The Bose I enjoy for casual listening (bedroom/background) but not "critical" are as follows: The 301's, and the 601 series III. They have the most "conventional" setup and sound quite large with direct bass. The 901 have a nice effect, but again... I prefer direct bass. I preferred the older "sealed bass" 901's. If I get "critical" I can hear the colorations and flaws. But for casual use, they are fun. And it is true: it's nice to hear both speakers from anywhere in the room, not just a narrow sweet spot.
