RPX and GPX are essentially the theater's branding of the Premium Large Format (PLF) which at this location includes a 3 story tall screen and Dolby Atmos surround sound. This is essentially the premium screen in the theater and costs about $3 more per ticket.
Equivalent to imax/dolby atmos
It's a sound and video enhancement in Regal theatre's. It's a maybe slightly better experience when viewing. I personally feel like the audio is almost too loud in the RPX showings. I actually prefer the general showing at Regal theater's. But some prefer the RPX.
