I'm running a pair of Triad 8" Omnirounds in my 10' by 18' by 8' high kitchen ceiling and they provide nice sound overall. Although they point "straight down", you can pivot the tweeter a few degrees to help with aiming the highs. Triad makes quality speakers throughout their line and are noted for their "architectural speakers" where placement or aesthetics is a challenge.
Their 8" size provides respectable bass, although you could add a sub like Rives suggests. I sometimes engage the "loudness" circuit on my receiver when playing them at modest volume and they sound suprisingly rich even without a subwoofer. One of the best features of the Omnirounds is they are designed with a closed back, which prevents sound bleed-through to the upstairs and provides a more predictable sound than open-back designs.
I power mine with a 100W Arcam 10P amp, but they are efficient enough that you could drive them with less, esp. if you have a powered subwoofer in the mix. Good luck with your system!
P.S. I used 14 guage 4 conductor speaker cable instead of 2-conductor pulled to each speaker to make sure they weren't starving since it was a fairly long run back to the amp., probably overkill but what the heck..
