Fohhn, LC-100, Line source speaker system, 240 W, 8x 4", 8 O, black

Passive loudspeaker system in weatherproof aluminium enclosure, equipped with 8 high-quality 4" wideband drivers with treated cones for optimum efficiency in speech reproduction. The line source speaker is intended for use in fixed installations where the highest demands for speech intelligibility and visual appearance must be met.

Passive 2-way loudspeaker system, optimised for speech reproduction

Passive loudspeaker system in weatherproof aluminium enclosure, equipped with 8 high-quality 4" wideband drivers with treated cones for optimum efficiency in speech reproduction.

With a short-term capacity of up to 960 W, the loudspeaker system can generate a maximum SPL of 127 dB. It has a very precise dispersion of 130° x 15° (h x v) and a frequency range of 120 Hz to 12 kHz.

The loudspeaker system has an extruded aluminium enclosure with steel bracings and is completely weatherproof (conforming to protection class IP54, in accordance with IEC 529 / EN 90529 standard). It is therefore ideally suited to both indoor and outdoor applications. Optionally available in all RAL Classic colours. Other colour catalogues or photorealistic finishes are also possible on request

To protect the loudspeaker drivers and electronics, the enclosure is fitted with a ball impact resistant, high-quality, sound permeable grille made from galvanized, powder-coated steel in the enclosure colour. 8 x M6 integrated screw threads on the base, rear panel and top of the enclosure are designed to accommodate mounting brackets.

Connectors: stable screwed terminal connectors for up to 4 mm² cable cross section with waterproof cable gland. Double connector blocks enable loudspeaker signals to be looped through.
