Merlin TSM speakers alignment

The alignment tool is for toe-in.  You can make one out of plywood or cardboard.  It's a right-angled triangle.  The base measures 2 1/8" . Height measures 11 7/16".  Set the triangle with the 90 degree corner at the front inside of the speaker.  Position the speaker so the hypotenuse is aimed directly at the center line of your seating position.  Done deal. 

Correction height is 11 9/16"

Thanks alot, will try to make one from cardboard!
