Totem Arro or Sttaf or Hawk??

You didn't mention anything about your other equipment. I used to own a lot of totem speakers, including the arro's, model 1, and a couple pairs of mani 2's. I thought the arro's sounded great in my den with a low power jolida integrated amp. I used the model 1's in a room your size with Macintosh equipment. I added a Rel strata iii for the low end. I would recommend this setup in your room depending on your amp. I used to have floor standing speakers in the room before the model 1's and it was very hard to get the sound right. When implementing the Rel, it was very easy to get the bass right since it was adjustable. With the floor standers like the hawks(which are excellent speakers in a bigger room), you don't have the room to get the speakers out into the room since its on the smaller size.
Just my opinion.

The arros performed very well in my small room with a jolida hybrid integrated. Surprising bass for a 4" speaker.
All the other Totem speakers I have had, I would agree about the power demands and have stated this in other forums. I ran my Mani 2's with a 200 watt Classe amp, but they really sounded the best when hooked up to the Mcintosh 1000 watt monoblocks. I was considering getting the Mcintosh 352 amp for a bump in power but after using the 1000 watt mono's, I would have had to go to the 500 or 600 series Mcintosh amps. Totem's are very nice speakers, but I ended up selling all my Totem's and going all Usher which are a little easier to drive plus they have the Diamond tweeter.
