Here's a fun way to justify buying cool tools!
You can use a Laser Level as a helper to a cell phone app to quickly and accurately determine the angle that a speaker location is at relative to the Main Listening Position. It's really simple. Make sure the AutoLevel feature is locked.
Place the laser level in the center of the MLP and aim it at the center of your front wall, tv, space between the Left/Right speakers, whatever.
Then plop your cellphone with a Compass app open on the laser. This will invariably not be at an orientation which will provide a number that allows for easy math. So change it.
Rotate the phone so the number is what you want it to be as a starting point.
Now rotate the laser/phone so that the laser points where you want the speaker to be located. In this case, it's going to be the angle I want to use for Front Width speakers, so I'm choosing 50°. Now move the speaker into the position relative to the laser line. Of course the photos are just examples, I don't have a countertop where I sit.
This same principle can be used for finding vertical angles, albeit with a little more difficulty. The app to use for this would be the Measure app and then choose Level. Also, you'll probably need to use some tape so the phone is a little more securely fixed with the laser.
