Voice Alarm-Series:
Loudspeakers for use with voice alarm systems

Fohhn's new LEN line source loudspeakers have been specially developed for use with voice alarm systems. The passive, 100V, EN 54-24 Type B certified loudspeakers have extruded aluminium housings with steel reinforcements, making them suitable for both indoor and outdoor use without requiring any additional weatherproofing.

All LEN loudspeaker systems are equipped with high-quality, full range, 4’’ treated drivers to provide optimal levels of efficiency in speech reproduction. The systems feature two-way technology with integrated passive filters that guarantee an even dispersion and the best possible coverage. An innovative, in-house developed waveform system (Fohhn® Source Division Waveguide) effectively suppresses side lobes, resulting in excellent levels of speech intelligibility for acoustically challenging venues with long reverberation times, such as airports, railway stations, shopping centres, auditoria and conference rooms.

LINEA LEN line source loudspeakers are available in five models, with lengths ranging from 20 cm to 220 cm. All RAL Classic colours can be supplied, with special colours and photo-realistic decorative surfaces (Fohhn® Texture Design) also available on request.
