“Here are some quick fixes for onstage sound: Try placingsidefills low on their side and angling them up with 2×4s. Thisreduces floor bounce and its resulting comb-filtering. Carpeting thefloor can be the cheapest way to improve the sound onstage. Toeliminate that ‘zone of confusion’ at the exact centerpoint between sidefills, angle one upstage a few degrees. Or use asingle small wedge downstage-center that's delayed to synchronize it tothe sidefills. If your singer stays DSC with a mic on a stand, tryflipping one sidefill's polarity for a clearer sound.”
