I've used various Bose oddments over the years, my overriding impression is that they do well for things like bars and restuarants, but put them next to a decent PA and they just can't keep up.
The "I put it on a par with any PA system in its class" ... well, most decent PA systems are not in that class, they are way above it. To be fair, for what the Bose kit is designed for (conferences, weddings, corporate sound reinforcement) its fine, but put any serious bass through a Bose rig and through a proper rig running say, double 18" bins on each side and a few kw behind it and the Bose stuff won't keep up. I find the top end harsh and lacking in detail.
Many years ago I was told Bose stood for "better get another sound engineer", I've yet to hear anything to convice me thats not true.
