B&W 803 d3. Is a 16 x 12 size room ok for this spkr?


Kinda like this speaker.  Amp size is fine and trying to assess if room size is ok too.

I think it should be fine. Your room volume (ceiling height) and open doorways also has to be considered. Nice speakers. A friend of mine has them and loves them.
Ceiling height I 7 1/2 ft. There is a ceiling fan, which may help scatter some waves.  Don’t like smooth plastic ceilings.
