A re-post from our archives -
I was amused to see Megan McArdle having problems positioning her stereo speakers because I once spent a frustrating year fiddling with that issue in our parlor with my ridiculously high quality but handsome 5 1/2', 175 lb. Legacy Focus speakers, which would be better suited for an auditorium, a barn - or outdoors. You cannot crank them up or it could remove my house from its foundation.
Good stereo speakers need to be at least 3' from the wall, away from direct sunlight, and 6-10' apart, depending on room size. Even so, there will only be one relatively small area in the room where the sound will converge properly. What if you want to sit somewhere else? You cannot sit in front of one speaker. (And don't even talk to me about that stupid "surround sound" fad of the 1980s.)
I finally gave up on doing it right, because it wouldn't work in the room, given the windows, fireplace, piano, and other necessary furniture. I even called Legacy and sent them a floor plan, and they were kind and helpful, but it just didn't work for the space. That marked the end of my pursuit of maximum recorded sound. It's a fool's errand unless you have a dedicated "listening room" like fanatic audiophiles do. Now, I'd just rather spend my money on hearing live music, and I mostly listen to music via my crummy old computer speakers.
My big Focus speakers ended up 24' apart, in corners, about 18" from the wall. Totally wrong, unless you are listening from the adjacent room. Makes me want to return to good old monaural and to heck with this stereo nonsense. I remember when my Dad bought our first mono cabinet "record player." Man, did that sound good. I even remember my kid sister playing "Meet the Beatles" on the thing, when the record came out. (I thought it was dumb music...at first.)
Here's a good how-to on speaker placement.
