The Martin Audio ADORN ACP-55T in white is a pendant-style ceiling speaker with a 5.25″ driver and integrated 70V/100V transformer, designed for architectural spaces with high or exposed ceilings. Its wide 150° conical coverage delivers consistent audio across large floor areas from fewer speakers, and the white finish blends discreetly into lighter ceiling environments.
