It is important to know the size of the room… but then I am curious what the shortcoming of less than huge speakers are. The constraint is typically the acoustics of a too small room. When a room gets too big… we’ll the small room problems go away.
If you build a 9’ triangle away from the front wall, side walls, and back wall… this is ideal. I guess unless the room is 100’ x 100’ x 12’ or something that begins to be more like out of doors. My Sonus Faber Amati Traditional are about this cost and my room is mid-large… sounds great. From my listening position. Bigger would overload the room.
So, after typing this, I realize I just have never had this problem… always the opposite.
