First thing that comes to mind is a pair of QSC K12. I personally have Mackie SRM450 and use them in a large gym for instrumental music concerts, and I think they sound great. I also use Anchor AN-1000x as fills Most people will tell you, however, that the K12 in comparison is a notch up in terms of smooth frequency response. Plus they look a bit cleaner visually.
In contrast, most non-powered speakers I have heard hanging in rooms don't sound good to me at all. But that's just my bias.
I don't use DSPs ... I run the house flat. The only EQ I use is low cut for non-percussion, and the occasional notch filter on input channels to deal with feedback from condensor mics that are close to the front.
do you know if they are passive?? thanks for your reply
