The HM25-G is a powerful loudspeaker speaker equipped with a compression transducer, all metal construction (even the inside of the speaker is metal), which offers an exceptionally clear sound. It is a unique unit in the market. It incorporates a high-quality 100 V transformer, which has three power sockets and a thermal overload cut-off switch. The APart technology prevents overloading of the amplifier thanks to its internal IMC protection device. This circuit controls the impedance of the loudspeaker, even beyond its nominal frequency range, and protects the 100 W amplifiers from overloads. The double cable grippers facilitate the wiring and connection of the HM25-G. Its casing is totally waterproof; it is supplied with an aluminum support that is also protected against corrosion, making it the ideal solution to be used outdoors, in public address applications and alarm signals in places where there is a high level of environmental noise.
