So I did exactly what you are doing. I have a nice pair of usher mini-X with the DMD tweeters. They sounded pretty good in my smaller room but something was missing. So I started looking at smaller floorstanding speakers and went with the revel f226be. I have a 15.5’ x 13’ room and hear revels sound so much more full and produce enough bass so no need for a subwoofer. Since you were looking at the revel bookshelf speaker, spend a few more $$$ and get the f226be speakers.
If you want to go with a bookshelf, look at the ps audio fr5, sounds bigger than it should.
