The Morel Sopran 622 loudspeakers are equipped with drivers developed and manufactured by Morel itself. High frequencies are handled by the Morel Acuflex tweeter with a 1.1-inch soft dome – a signature feature of the brand. The rest of the frequency range is reproduced by a 6-inch driver with a carbon-fiber diaphragm featuring a honeycomb structure, providing an exceptional stiffness-to-weight ratio. In practice, this results in fast transient response, low coloration, and bass that remains tight and articulate even at high volume levels. The crossover frequency is set at 2.2 kHz.
