We are a function / dance band doing pop covers and traditional "dance" music with occasional excursions into FM rock if we can get away with it. Tend to be quite bassy on the pop / disco / "modern" dance / rock stuff but can still pull it back for quicksteps / waltzes / ballands etc.
Even though I say it myself the system sounds surprising good even at very low levels. When driving harder the capabilties of the bass units really give it some punch.
I don't think we've ever got near the limits of the system.
The PA is this:
Behringer 2642 desk (I think)(8 mono, 4 stereo, 4 extra stereo, 2 subgroups) into KAM Graphic (set to give gradually increasing treble boost from about 1k up to 16k finishing at +12db) into Studiomaster Active Crossover @ 150Hz into Yamaha driving the Bose's and an Audiotech 1200P (budget GB no longer made, soon to be replaced possibly by Behringer or another Yamaha) about 600 a side into 4 ohms (but uncalibrated attenuation so the bass balance is set by ear) driving the subs which are 4 ohm Peavey Black Window 15" in homebrew ported cabinets.
The Bose are driven by a Yamaha P3500s amp set to -10db attenuation. I think this amp could get to 450 a side into 8 ohms. I suspect we've never got past about 200 for any sustained period.
I don't think we've ever driven the mixer consistently into the red (i.e. over 0db on the meters). The graphic and crossover are set to give no gain so (apart from the effects of the graphic) the level coming out of the desk should be that reaching the amps.
