Room size for B & W Nautilus 802


I am looking to upgrade from Revel F-30s to B and W 802s. I think from my listening experience it is a better speaker for female vocalists that I listen to all the time. The room I want to put it in is 16 feet wide by 40 feet long. I am wondering if the size of the room that I am putting the speakers in may be too small? Please let me know from your experience with this speaker.

Thanks. I have a Bryston 4BST and BP-25 preamp right now. I think I have a good power. I was thinking of adding a second amp and running them mono at a later time.
I.M.O. - would sound better if you Bi-amp w/ 2 4B-St's, then bridging them into 700 wpc monos.
I think that the B&W's do require a very large room. Before you buy, check out the Tannoys and Kef, especially the Kef Referance 205s.

I settled on these after lots of auditions. B&W really didn't match up with the Tannoy or Kef.
Unclejeff, what do you think of the Kef Maidstone speakers? I have not auditioned these have you?
