Many are confused by FRONT wall; it's the wall BEHIND the speakers. 

I agree!

Precedence effect:

Below is a quote from my speakers tech manual:

''2. Stereo imaging will be improved The frequency response of the new monitor design is quite uniform, even at angles sufficiently off axis both horizontally and vertically to be unlikely listener positions. However, this results in more uniform room reflections which contributes to a stable virtual source that does not change with frequency [Queen [13]). In addition, increased toe-in can be used with no degradation of the direct sound field, rf enough toe-in is used for the axes of the systems to cross somewhat in front of the listener, then the level precedence effect can partially offset the time precedence effect (Haas [14]). This contributes to a more stable stereo image as the listener's position varies along the length of the control board.''

The image is extremally fragile when out of the listening position even by a few inches. 30 degrees or more off axis you can even lose the far speaker completely. 

I like well designed (CD) horns for home stereo playback. Listeners both standing and seated can move up to 60 degrees off axis and still get the same frequency response as center, even in close proximity to the speakers. See below page 8 theory of operation:

Five feet from the front wall

Just what does "X" feet from the front wall mean? Is this from the front of the speaker or the back of the speaker?

The front baffle of the speaker. 😎
