What Is Rpx in a Movie Theater? the Secret Difference Regal Doesn't Plainly Advertise
By Robert Thorne
The most frequent question ticket buyers face at checkout is whether RPX holds its own against dedicated premium brands. The differences boil down to proprietary control versus exhibitor discretion.
IMAX dictates room dimensions, viewing distances, dual-laser setups, and proprietary aspect ratios (expanding up to 1.90:1 for digital and 1.43:1 for select 70mm venues). Dolby Cinema enforces high-dynamic-range dual Christie laser projection (Dolby Vision) with a certified 1,000,000:1 contrast ratio alongside spatial Dolby Atmos audio. RPX, by contrast, operates on a sliding scale.
| Feature / Specification | Regal RPX | Digital IMAX | Dolby Cinema |
|---|---|---|---|
| Average Screen Size | 45 to 70 ft width (varies by site) | 50 to 80+ ft width | 50 to 65 ft width |
| Aspect Ratio Capability | Standard scope (2.39:1) & flat (1.85:1) | Expanded 1.90:1 (or 1.43:1 GT venues) | Standard scope (2.39:1) & flat (1.85:1) |
| Projection Standard | Single or dual 4K Laser / Xenon | Proprietary Single/Dual Laser or Xenon | Dual 4K Laser (Dolby Vision HDR) |
| Audio Configuration | Dolby Atmos or custom unbranded spatial | Proprietary 6 or 12-channel uncompressed | Dolby Atmos (up to 64 channels + seat transducers) |
| Average Ticket Surcharge | +$4.00 to +$6.50 | +$5.50 to +$8.50 | +$6.00 to +$9.00 |
| Seating Baseline | Plush rockers or premium power recliners | Standard stadium seating (rarely recliners) | Full motorized leather recliners standard |
The comparison reveals why moviegoers often experience differing results with RPX. In an auditorium fitted with updated laser projection and licensed Dolby Atmos, an RPX screening closely mirrors Dolby Cinema performance for a lower ticket price. If the auditorium relies on older unbranded equipment, the gap between RPX and a standard theater narrows considerably.
