If (non-thin) full-range sound from a petite speaker is the goal, I have to second the Carolina Audio recomendation- really must be heard to be believed. The Konus Essense is a similar (but more expensive) design that has been well reviewed. They are less picky about electronics or placement than any speaker I have owned.
Spendor S3/5s also sound pretty robust for their size. Totem speakers might also work.
