IMAX Sound Systems

IMAX sound has always been generations ahead of nominal theater systems. Early systems used a 6 track plus sub-bass audio tape system synced to the film.

Over time this was replaced with a CD based system. The IMAX sound systems (by Sonics which IMAX purchased long ago) feature a full 10 octave dynamic range while even modern conventional systems are limited to 6 octaves.

A classic IMAX theater uses 44 speakers and up to 36,000 watts to power the speakers. MPX theaters may be anywhere from minimally better than other theaters to a full blown IMAX system depending on the contracts and costs.
