In April 2010, Regal launched RegalPremium Experience (RPX), an upgraded theater format. Each RPXtheater features a 60-foot screen, dual 30,000 lumen digital projectors, a 7.1 sound system, a Dolby Atmos sound system or an Auro 11.1 sound system with 273 loudspeaker components including eight 21 inch subwoofers
RPX stands for Regal Premium Experience, which is supposed to have better picture and sound quality than IMAX, complete with a giant, IMAX-size screen.
