I think Bose conceived this system as a mono system; they argue that from most points in the audience a stereo effect wouldn't be noticeable anyway. So I would only plan for one single L1 compact, but I fear I would miss the stereo. I'd like to get your opinions on a) the power and sound of the system and b) whether a mono system is worth considering at all. (Buying two of them is no option for me at present).
