TRX20 series
20W Metal horns

The horn speaker units of the TRX20 range, featuring a watertight design and intended to guarantee the highest possible level of sound pressure, are particularly suitable for outdoor use even in difficult weather conditions. The housing is made of die-cast aluminium with stainless steel screws and brackets, while the horn is made of aluminium sheeting. Each model has a driver unit with a line transformer, a rear switch for selecting the operating power (five positions) and a terminal for correct connection to earth. The TRX20-EN model has been specially developed for use in voice alarm signalling systems and are equipped with a thermal fuse to ensure the protection of the loudspeaker connection line in the event that a possible fire knocks out one or more of the loudspeakers connected to it.
