Re: Measuring toe-in
Here is a quick calculator for you. Please double check my result!
All you need to do is decide upon distance d1 from the rear wall to the speakers nearest back corner (in mm, cms or inches) and the toe-in angle which in this worked example is 10 degrees.
Then, using a pocket calculator find Sine 10 = and that number you fit into a equation as you do the distance d1. The number that falls out of the calculation (d2) you add to distance d1 and that tells you how far away from the rear wall the furthest back corner of the speaker is.
Hope that helps.
