I'm not the sound guy in our band I figure I'll help out with some info gathering Apologies for lack of all info here but hopefully I have enough to get a few opinions. We mostly play smaller bars and clubs with occasional outdoor gigs (not talking festivals or anything here).
We've been using a couple Mackie 1801 subs (iirc) with some mackie powered mains (model escapes me). The board is a new line 6 soundscape (so far very cool), monitors and mains are all active. Those speakers will be moved to monitor duties, joining a couple other identical ones.
Bass player/sound guy is looking for lightly-used gear that he's confident in (as he says, no CL for active gear). So far he's looking at a pair of QSC 15-inch speakers (apologies, don't know exactly which) and the Mackie SR1350. We expect the QSC would be great but $ is a factor. We don't know much about the Mackies and would welcome any opinions.
Edit: QSCs are model 153i apparently.
