Mrjstark is correct for most speakers, and correct about the mirror technique.
Note that line-source speakers don't have a significant floor and ceiling first reflection. Note that bipoles and dipoles will have a significant first reflection off of the wall behind the speaker. And if the speakers have a well-controlled radiation pattern, it's possible that enough toe-in could essentially avoid the first near-side-wall reflection.
