A small change in speaker toe in of less than an inch can snap into focus the center image.
That's the power of small.
But, it goes deeper.
Once the center image is stabilized your emotional connection to the music changes. You relax. No longer are you working hard at wondering if what you're hearing is right, or moving your head enough to center the singer.
You let down your guard and the music pulls you in.
An inch can make all the difference—not in the big scheme of things—but in the little scheme. The one where you are relaxed enough to forget everything else and engage with the music.
The power of small is found in helping us remove the barriers to great sound.
