You might want to consider Revel Performa F30s; I am running them in a 12.5x19.5x8 room with a Jolida SJ502a which puts out ~60Watts/ch (I am using Ei KT90 power tubes; I'm not sure if that increases the power at all, but the amp is rated to deliver 60/ch).
I wanted a speaker that did deep bass as well as a really nice midrange and good detail/air etc. Having auditioned several in the 3-5k price range I settled on the Revels and am very happy I did. I was a little concerned that the amp would not be able to drive them well, but it has no trouble at all (I rarely take the volume past 25%; beyond this the SPLs become quite uncomfortable, though not at all distorted- I just can't listen that loud for any length of time :).
As always, audition before you buy :).
