Bosch LC4-UC06E

Wide coverage ceiling speaker. 6″, 6 watts, 100 volt line & 8 ohm.

EN54-24 compliant if optional back box / fire dome is fitted.

The Bosch LC4-UC06E ceiling loudspeaker can be used for a wide variety of indoor public address applications to provide excellent speech and music quality.

Compliant with EN54-24 and BS5839 part 8 when used with the optional LC4CBB or LC4MFD back box / fire dome. (see related products)

There are 3 variants in the range rated at 6w, 12w, and 24w all with the same 200mm diameter grille. The LC4UC06E is rated at 6 watts, 100 volt line and 8Ω.

New CosCone driver technology used in this range, delivers outstanding sound quality from a small sized unit, ensuring a wide and equal spread of all octave frequencies and eliminates high‑frequency beaming.

Fewer loudspeakers are needed to cover a given area, and the noticeable “fading” that can occur as a listener walks from one loudspeaker to another area is eliminated.

The LC4 range includes a back‑box and metal fire‑dome – the use of either ensures the LC4 range comply with EN54-24 and BS5839 part 8.
