The Fonestar SKY-3XT is a 3" ceiling speaker with a 100 V line transformer, designed by Fonestar to combine aesthetics and functionality in professional sound installation projects. Its frameless, low-profile aluminium grille resists oxidation and gives a discreet, modern finish. The grille is removable, locks into place by rotation, and can be customised: the logo can be removed and the grille painted to suit the surroundings.
With IP66 protection against dust and water and materials that resist corrosive environments, high temperature and humidity (sauna), it is ideal for demanding indoor and outdoor public address projects in hospitality, retail, hotels and beyond.
