The IMAX theater in Little Rock, Arkansas, is located at the Aerospace Education Center. It uses specially designed theater and technology, where every seat is the best seat in the house. It has a screen six stories high (other IMAX theater screens around the world are as high as eight stories) and a six-channel, 16,500-watt sound system. IMAX utilizes the largest film frame in motion picture history, three times larger than standard 70mm film. The IMAX system has its roots in EXPO '67 in Montreal, Canada. Canadian filmmakers/entrepreneurs Graeme Ferguson, Roman Kroitor, and Robert Kerr, decided to design a new system using a single, powerful projector, rather than the cumbersome multiple projectors used at that time. IMAX premiered at the Fuji Pavilion, EXPO '70 in Osaka, Japan. In 1971, the first permanent IMAX projection system was installed at Ontario Place's Cinesphere in Toronto, and the IMAX DOME (OMNIMAX) was debuted at the Reuben H. Fleet Space Theater in San Diego in 1973. The images are of unsurpassed size, clarity and impact and are projected onto giant rectangular screen. In the case of IMAX DOME (OMNIMAX), onto domes as large as 88' 5" in diameter. The IMAX six-channel, high-fidelity motion picture sound system, with sub-bass, is manufactured by IMAX subsidiary, Sonics Associates Inc. Sonics Proportional Point Source Loudspeaker system specifically designed for IMAX theaters, eliminates variations in volume and sound quality over the theater seating area. This allows all members of the audience to experience superb sound quality regardless of where they may be seated. IMAX projectors are the most advanced, highest-precision, and most powerful projectors ever built. Their superior performance and reliability is the unique "Rolling Loop" film movement, originally invented by Ron Jones.
