100 лет динамиков в кинематографе

The history of motion picture sound has been well documented over the years, covering all aspects of film and disc systems, microphones, recorders and amplifiers. But there is a scarcity of information on the development of the cinema loudspeaker which has always been the weakest link in the chain.

Here are the known facts.
