Optimal Audio UP4O White Pair - A pair of discreet 4” ceiling speakers that provide consistent coverage and clear sound in various commercial environments, such as hotels, shops, bars, and restaurants.

With the Grille 1 accessory, it can be enhanced with a bezel-less look and is available in both white and black.
