4 x 9 cm (1.6" x 3.5") full-range speaker with wood membrane and sturdy plastic basket. Flat, lightweight design using neodymium. The interaction between the individual components ensures an extremely linear sound reproduction quality right down to relatively low frequencies, so that the loudspeaker can also be used in miniature HiFi speakers.
