Rosetree,
I have been using Bose speakers, L1 Mod 1 and now the Bose L1 Compact, and would not think of using anything else. Here are my reasons:
1. Sound dispersion none others can match
2. Very Light Weight
3. Very Easy To Setup
4. Quality Quality Quality
5. Oh Yes, They sound great too.
As for Stereo - Don't believe it for live gigging. The only person to actually hear the Stereo effect is you. I sold one of my Bose compacts and have used only one for over a year - doesn't make a bit of difference to the audiences. Now if you got money to waste or just have to have stereo for your own enjoyment - buy two.
I have no experience with the other speakers you mentioned so can't comment on them.
