The Bosch LC4-UC12E ceiling speaker 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.
There are 3 variants in the range rated at 6w, 12w, and 24w all with the same 200mm diameter grille. The Bosch LC4-UC12E is rated at 12 watts, 100 volt line and 8Ω. 162mm cut-out.
New Cos Cone 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.
Its extremely wide opening angle (180° at 4 kHz) delivers high-quality audio with a wide frequency range over a large area, so you can use fewer units than is normally recommended.
The LC4 ceiling speaker 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.
