I think if you are going to speak in absolute terms on this subject, then yes, it's difficult to compare a monitor speaker to a floorstander apples/apples. However, speaking in relative terms it really depends on which specific floorstander you are using for comparison and which monitor - they're not all created equal, for sure.
For example, I have a pair of Hales Revelation One monitors that, while not truly "full range" in absolute terms, can definately provide a very rewarding experience even on full orchestral music. These monitors may be an exception, but set up properly on stout stands in my living room (14 x 17) and driven by an Arcam Alpha 10P power amp, these speakers truly "play large" for their relatively small size. I've listened to the soundtrack to "Immortal Beloved" at fairly high volume and they really hold it together.. cellos, bass, piano and all...lots of "body" and "weight" to the instruments and the tone is pitch-true.. amazing!
