Simple Tweaks Used at Audio Shows to Help in System Setup

I just got back from doing an audio show in Hong Kong, and I am still a little jet lagged. The Audiophiles were really out in force at the show; you could barely walk down some of the aisles. The photo illustrates what mean. I saw a lot of nice audio equipment, at the show, not available here in the USA (no surprise).

So much for my rambling, this simple tip (see steps below) will involve a simple string, a good friend, and a little time.
1. Have someone sit in the center or the sweet spot of your listening room.
2. Have them hold the string to the tip of their nose or center of their body.
3. Pick one of the speakers and go to the outside edge of the speaker; keeping the string tight.
4. Hold the string at the point where it meets the outside edge of the speaker.
5. Take the string to the second speaker’s outside edge. The section of string should be the same length.
6. Adjust the speaker to match the first speaker if there is a difference in distance.
7. Take the string back to the first speaker you started with and go to the inside edge of the speaker. Be sure to keep the string tight.
8. Hold the string at the point where it meets the inside edge of the speaker.
9. Take the string to the inside edge of the second speaker. Again, the section of string should be the same length.
10. Make any adjustments necessary for both speakers to match.
11. Check the distance to the outside edge of each speaker again to make sure it did not change during adjustments.
12. Double check the inside edge distances to make sure they match.
13. Sit down and listen.
14. If any adjustments need to be made, then adjust one speaker at a time and repeat the procedure again.
Let me know what you think of this simple technique. I’ll post another simple tip next week.
