horizontal

Are there any objective means of determining the degree of speaker toe-in, or is it best determined by ear? I feel it has something to do with horizontal directivity and beamwidth measurements, and possibly room measurements. Any help would be appreciated.

I've had these two speakers for a very long time, but I've never really gone into a detailed comparison between these two side-by-side before. This exercise is going to be divided into sections, so just skip ahead to the areas of interest to you. Also, I'm going to be focusing on the Sceptres...
