 The larger diameter of 25 mm / 1”, the Ci5 T25FM-CA has an excellent wide dispersion and off-axis response, allowing the creation of an impressive sound image and soundstage – even in OEM installation spots. With its ceramic-coated aluminum dome, it features a balanced frequency response and excellent decay characteristics. As a result, high frequencies are reproduced even more clearly and realistically.
