B&W N800, 800D, 802D for my room 16x17x8

I use 802N's in a 13 X 24 room with 300 watts, they are still a great value here in the used market. Your the room size itself could pose more of a problem because the two walls are equal length. Make sure the sound accoustics are in place first because without proper treatment any speaker will not perform to it's capabilities.

I would get the 803D! they look awesome with the FST driver and 3 additional front woofers.

It may sound typical with B&W but I have been listening to them since mid 90's because they "rock" & simply play everything great.

My room is 14'(front)X24'(deep) and use N802's and a 108" screen, There is 7'6" between them and sit about 10' back to the front row seating. I play both music and movies with excellent results. I also use stereo B&W ASW800 subs up front for just a little extra definition and authority but blended very naturaly. They are not needed but icing on the cake with the N802's. Best of luck with your results.
