The Belltron TR-3B horn speakers for the outside offer a stereo performance to cover large sound ranges, fitting perfectly into the surroundings where they are installed, sometimes becoming even unnoticeable owing to their small size.


The Belltron TR-3B speakers  allow the sound diffusion in specific directions, sometimes difficult to reach. Due to their power, the sound can reach long ranges re- calling the faithful to prayer.
