In this same situation I have used both Rogers LS3/5a (also available from other manufacturers as noted by yogiboy) and Allison CD-6 (available on the used market from time to time, but you must be patient). Price points are very different including the variations of the LS3/5a. ZuAudio also makes a couple of speakers for this purpose - Cube and OmenBookshelf; but I have not heard either of these.
