Tilt ‘er back

If you’re looking for a quick and easy fine-tuning technique, try tilting the speakers forward or backward relative to the listening position.

This is a time-honored tweak that not everyone’s familiar with, but it sure works great. The easiest way to do this is by using a CD jewel case under the front of your speaker for tilt back or under the rear of the speaker for tilt-forward. The half inch or so depth of a CD case is about perfect for a tilt change. You can use multiple cases to arrive at your final position.

What you’re doing is aiming the tweeter slightly above or below your ear—off-axis. Tilt back and above your ear will open the soundstage and offer a more airy presentation. Tilt forward and the opposite happens.

For this exercise, I like to start a well recorded multi-instrument piece like Reference Recording’s Red Norvo How’s your mother in law. As I tilt back the speaker the image gets deeper, wider, and more open, but it also loses a bit of upper harmonic energy. Heading in the opposite direction I increase the HF energy (depending on how your tweeters are now aimed) and gain more life.

Once that recording is dialed in I put on one of my favorite setup discs, Buddy Holly’s True Love’s Ways. Here I am listening for the immediacy of the voice and make my final tweaks to get it just right.

Nice to have an easy tweak we can try at home.
