Plus infinity. I'm surprised this wasn't brought up sooner.
In a near-field setup, where you're just a few feet from the speakers and you're hearing mostly direct sound, then the sound of the speaker itself wll be the most important factor -- except for bass, where the room always exerts its influence.
But in any larger room, any configuration where room reflections come into play, then room+speakers=system. I include placement within the room as part of the equation, and to the extent that the room constricts placement, the room is even more important.
Room correction like Audyssey can help somewhat; physical room treatment will help even more but it takes some expertise to accomplish. Otherwise, the same speaker can sound completely different in a long, narrow room with wood floors vs a cubical room with lots of upholstery, and you won't be able to predict which speaker will sound better in which room without either extensive detailed knowledge of both the room's and the speakers' acoustical properties, or the simple expedient of trying them out.
