I like the ProAc D40 mentioned above too. I don't know about specific models, but I have also like J.M Reynaud speakers (the ones I heard did NOT fit the floorstanding, narrow profile requirement). I would also add to the list of contenders the YG Carmel (a little out of the price range but very good) and the Neat Momentum LX-6. While the Audionote AN-E also does not fit the narrow profile requirement, it is a speaker designed so it can fit close to the corners of the room so it can be unobtrusive as well. The Gradient Revolution is a reasonably compact system that can be placed very close to the wall/corners (VERY flexible in the way it can be used). I don't know if any Gershman model fits the price point or has the right profile (they are odd looking speakers), but they do deliver good sound.
Good luck on the search.
