802D vs 800D vs 803D in Small room with open plan?

I've noticed B&W 800D's and B&W 802D's aren't all the different in used prices (2000ish). Is it worth going with the 800D's over the 802D's over the 803D's considering my room in feet is 15x17x10 with with an open kitchen, dinning room, entry and breakfast nook attached. Kitchen is 8 ft ish by 15ft ish and dinning room is 15ish ft by 10ft. Nook 10 x 9. All have or 11 ft ceilings. Maybe ASCII art will help. The area show is all open to each other. Speakers would be in the living room. I'am also guessing the size because it has been a long long time since I've measured or seen the floor plans
