Details

The Bosch LC4-UC12E 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 LC4UC12E is rated at 12 watts, 100 volt line and 8Ω.

The 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 Bosch LC4-UC12E will comply with EN54-24 and BS5839 part 8.
