Quote:1. Note where you sit and where your head is at normally.
What placement is best for 2.x systems?
2. Adjust the height or angle of your speakers so that if the tweeters shot you, they'd be at ear level; anything below neck level is too low.
3. Place the speakers so as to be at an equilateral triangle with your head (use a tape measure); try to keep them at least 6" away from any surface (wall, monitor, etc); wider than equilateral is better than narrower if you need to spread them out to fit peripherals. If your desk is against a wall, the closer they are to the wall, the more low frequency sound will be accented: keep that in mind if you want to adjust how it sounds later. Avoid overhangs (top cupboards) and if you have them, make sure the front of your speakers are in front of the overhang.
4. Get your favorite good quality recording CD of an artist that sings solo with very little instrumental and play it on repeat while doing the next step. I use Sarah McLachlan's Christmas CD.
5. Start with the speakers pointed straight out (square with the desk), then slowly angle them inward (to start pointing at your head) until you can't hear the artist's voice from either speaker, but only coming directly out of the center of the wall in front of you. Be sure to move both the left and right in by the same amount. Don't get discouraged with this: it takes quite awhile to get right and you'll probably need to switch between different songs/artists until you find the right spot.
6. Switch your music to something with tons of very clear instruments, such as an orchestra or good quality sound track.
7. While this is playing, try adjusting just one of the speakers (left or right) by very, very tiny bits out and in until everything sounds "right" (you hear more details than a moment before or it seems "louder" or "clearer" for some reason). This is _very_ hard to do without using an SPL meter. What you're trying to accomplish is to get the two speakers to be in perfect phase when they hit your ears: meaning that the crest of the same sound wave hits your left ear at the same time it hits your right. This step took me almost 2 months of tinkering when I bought my A5+ without using an SPL meter, so don't worry if you can't get it right away.
