The CirseSound was the first Cirse projector with an integrated amplifier. It was the successor of the Cometson. It shared many aspects, such as the film transportation mechanism with the silent Missouri. It was widely admired and built a strong reputation, quite remarkable for a projector that was only produced for four years. Its production was discontinued by the end of 1962.  Its successor, the Silma Sonik 8 had been delayed by strikes in Italy and did not appear until 1963.
