What Is an RPX Movie?
RPX and IMAX are premium movie proprietary systems. The two systems differ in setup, audio system, screen sizes, video capabilities, and more. In addition, each has its own advantages and shortcomings.
What is an RPX movie? RPX is an abbreviation for Regal Premium Experience. It is a theatre experience like IMAX, including immersive sound systems, big screens, and premium laser and digital projectors. RPX falls short of IMAX in image optimization and projection technology.
However, it is still a great experience as it overshadows IMAX with its suitability for all movie formats, including 2D and 3D. Moreover, it is much better than any conventional theatre since it offers premium seating and a large screen. It is best suited for dialogue-focused film genres.
What Is IMAX?
On the other hand, IMAX is a theatre experience with immersive sound and visual systems, curved screens, and laser projectors. It is superior to RPX in projector technology, immersive systems, and image optimization, but falls behind in premium seating and affordability.
Unlike RPX, IMAX is best suited for the 3D format. With its immersive sound and visual capabilities, IMAX presents 3D images in unparalleled brightness and quality. This capability allows you to experience a cinematic experience unlike any other. However, to enjoy this experience, the film has to be action-oriented with stunning views. Hence, IMAX is ideal for science fiction and action films.
RPX vs. IMAX: What’s the Difference?
The RPX vs. IMAX debate is defined by seven key differences, ranging anywhere from comfort to technology to screen size and beyond. Without further ado, let’s dive in.
Comfort

Comfort is the predominant criterion for selecting a preferred theatre. In this regard, IMAX theatres fall behind RPX. However, this is not to say that IMAX theatres are uncomfortable, given that they provide comfortable seats with higher backs and premium leather covering.
These premium seats are custom designed to ensure an unobstructed view from any angle. With these specifications, each viewer is assured of an immersive experience despite the seating arrangement.
On the other hand, RPX theatres are a pinnacle of comfort. They prioritize their viewers’ comfort by providing reclining leather back seats with extra padding. These seats are much broader than IMAX’s, with high backs and headrests for extra comfort. Moreover, each seat leaves enough room for viewers to walk around, even when reclined.
Technology
IMAX is a forerunner when it comes to technology. Its utilization of a curved larger screen and laser projection produces some of the most incredible pictures. In addition, the curved screen provides 3D video effects that make pictures clear and immersive even with 2D movies.
Furthermore, IMAX utilizes 4D technology and a 12-channel audio system. In IMAX, speakers are positioned overhead for a more immersive experience. Unfortunately, IMAX movies must be shot using a special IMAX camera due to their technological requirements.
When it comes to technology, RPX is always close behind. With its constant innovation, RPX ensures that cinemagoers have a fantastic experience. Recently, RPX introduced their 4K laser projector with 33000 lumens and a 1870:1 contrast ratio.
Unlike IMAX, RPX screens support every possible video format, 2D or 3D. This unique nature makes RPX the ideal choice for watching various movie genres.
Screen Size
IMAX’s wall-to-wall screens are renowned for being larger than RPX’s. They are typically 70 to 100 feet long and more than 50 feet tall, making them nearly six times larger than the average movie screen. With such size, the screens create outstanding visuals with a precise contrast ratio.
RPX screens, on the other hand, are flat and much taller. A typical RPX screen measures 45-70 feet long and 60 feet tall, depending on the theatre size. Despite the different sizes, IMAX and RPX have equal build quality, since they are manufactured in the same factories.
Video Quality

With high fidelity and 4K movies dominating the market, video quality is essential to the cinematic experience. Therefore, finding a picture format with the best video quality is crucial when visiting cinemas. In this respect, both RPX and IMAX have their benefits and shortcomings.
For example, IMAX is best suited for 3D movies with stunning visuals and many action scenes. It is also ideal for 2D films since curved screens offer better video quality and somewhat 3D effects. However, IMAX could do better for movies with a heavy emphasis on dialogue rather than visuals.
RPX is a much better choice for movies with heavy dialogue. Additionally, RPX screens are dimmer than IMAX, making them more comfortable. This decreased brightness reduces eye strain, especially when watching 3D films.
However, due to their flat screens, some 2D films do not look as good on RPX. Furthermore, with viewers seated further from the screen, the experience can feel unsatisfactory.
Sound Quality
IMAX’s sound quality remains superior to RPX’s. Its superior 12-channel sound system offers an immersive and high-quality sound experience. In addition, IMAX theatres have their soundbox positioned overhead, which further improves the immersive experience.
Although IMAX has better sound quality, RPX is not far behind with its modern RPX theatres using 7.1 audio channels. Moreover, their speakers are embedded under each seat, creating a unique audio experience. However, while some enjoy this experience, others find the vibration distracting.
Overall Cinematic Experience
IMAX performs significantly better in creating a cinematic experience. Its overhead speakers, laser projectors, and curved screens create an unrivaled immersive experience. Furthermore, its crisp pictures and perfectly positioned seats make the view stand out.
RPX, on the other hand, focuses more on the viewer’s comfort and creates a cinematic aura. Their reclining wide seats with high backs, ample leg room, and a headrest provide unmatched comfort when watching a film.
Ticket Cost
Although still affordable, IMAX ticket prices remain consistently higher than conventional theatres’. Alternatively, the RPX ticket prices may be high or low depending on the seat quality and technology (3D, 4K, or laser projector).
