Those 801s likely will output way too much bass energy and overload the room. It's simply the laws of physics. I speak from experience having had floorstanders (B&W N804s) in a 10x10x8 room for many years. Finally went to stand-mounts which have made a world of difference for the better.
B&W 801’s
I purchased a new set of speakers for my primary listening room and I am thinking about moving my B&W 801’s up to a spare bedroom. Any thoughts on placement in a smaller room? The room measures approx 15x15 with 8 foot ceilings. Is it at all doable? Looking for opininions.
