With its 10 mm apparent thickness and pure white colour, it easily blends into a corridor or room ceiling once it is installed. The clean, well-made design allows this product to come with quality sound.Harmonys Indoor IP Ceiling Speaker is easy to install, once you have drilled the right size hole in the ceiling, all you have to do is flush mount the speaker. The mechanical springs keep it in place. Its IP connection makes it easy to configure since the loudspeaker uses the building’s existing IT network.
