However, Bose seems to have hit it. On Thomann.de, there are already three customer reviews with 5/5 stars each. The two German-language text reviews sound very promising, one of them from a DJ who has used a single S1 Pro for a wedding DJ job (probably rather small, but nevertheless).
If I didn't care about $1,200 more or less, I would definitely give a pair of them a try. But I do care...
