At the 2009 Coachella Festival in Indio, CA, Rat Sound Systems assembled a huge main stage system with twin line arrays comprised of 15 L-ACOUSTICS K1 enclosures topped by eight K1-SUB boxes and tailed by three dV-DOSC downfills. Additional arrays of eight K1 plus three dV-DOSC provided far left and right side coverage. Power for all systems was provided by numerous LA-RAK touring racks loaded with LA8 amplified controllers located under the stage.
