HM25-G Metal Compression Driver Horn

The HM25 is a very powerful full metal horn loudspeaker with a compression driver. Even the inner horn part is made in aluminum, which makes the HM25 unique.

The HM25 is equipped with a high quality 100-volt transformer with three power taps, including a thermal overload cut-off switch. This prevents any overload of your amplifier by controlling the impedance with the unique IMC protection device inside. This circuit controls the speaker's impedance even beyond its nominal frequency range and protects your 100-volt amplifiers from overload.

The double cable glands allow easy wiring and connection of the HM25. The housing is totally weatherproof and its supplied aluminum bracket is also corrosion protected... ideal for long distance speech and alarm sounds in evacuation systems indoor or outdoor.

Exceptional sensitivity makes the HM25 suitable for the toughest circumstances including high speed railway tunnels and stations, a warehouse full of loud machinery, or a school full of crowded students. The HM25 is so powerful that you can be sure everyone hears your message loud and clear.
