The dispersion pattern of HF horns is the horizontal and vertical coverage in degrees. Stereo imaging is how accurately a stereo signal is reproduced by a pair of speakers. If you intend just to plonk a load of boxes in one spot, then you don't need to worry about stereo. A single stack will be in mono, so the HF and MF sections can be driven by just a single amp channel each. So the minimum number of amp channels required for an active 3 way mono system is 3, for an active 3 way stereo system is 5 ( bass frequencies are omnidirectional, so they don't need to be run in stereo).

I will be using as both 2 stacks and 1 stack.

What would happen if I had x2 horizontal 1 above the other? (I’m not questioning you just if I know why you don’t do something it makes more sense!)

I have seen when I look at other Sound systems rows of horizontal horns I presume this is because they have more output below to balance? Or that they like more high?

You'll will learn a lot from from it especially coverage and dispersion etc. It's a  handy little 'bible' I think I got it it 25 years ago I'm sure they update it a bit but a lot of useful information. Second hand hand on eBay won't cost many pence.

Still quite expensive on eBay in uk as only copies are in US. It’s nice to have a hard copy as it’s easy but I’ve searched and found it on GoogleDrive as a PDF https://drive.google.com/file/d/0B9Ka-yX8YG6KVEJVNjVpNFVOY0k/view?resourcekey=0-ZVVgTWKylltbOwRVrbU_NA
