Jim Power's Toe-in Technique

My technique for ideal toe-in is pretty low tech but extremely accurate. Get a flashlight. Sit in the listening seat. Hold the flashlight directly above the top of your head. Aim the beam of light at the electrostatic element of each SL3. You will see a vertical streak of light reflected off of the film inside the grid. It will be a very narrow and distinct vertical streak. As you change the toe-in of the speaker, the vertical streak will move across the front of the speaker. Toe the speaker until the light streak is between 1 ½ to 2 inches from the edge of the wood trim on the inboard side. In this position, the SL3s will be aimed past you to the outside. In other words you will not be facing the dead center of the speakers. You will be facing the inner 1/3rd of the panels curve.
This technique works extremely well regardless of the distance to the speakers or even between the speakers. It will also provide you with the flattest response across the bandwidth.
Hope it works for you, jp
