Sound spheres are pendant sound projectors designed to be suspended from the ceiling by their connecting cables. Their excellent sound spread makes them ideal for use in buildings with high ceilings, such as hypermarkets and superstores. The LS1‑UC20E‑1 is a powerful 20 W pendant sphere loudspeaker, intended for high quality speech and music reproduction. The state‑of‑the‑art design is matched to both modern and traditional style environments. The loudspeaker is suitable for use in voice evacuation systems.

Voice alarm loudspeakers are specifically designed for use in buildings where performance of systems for verbal communication announcements is governed by regulations. The LS1‑UC20E‑1 is designed for use in voice alarm systems and is EN 54‑24 certified and compliant with BS 5839‑8 and EN 60849. The loudspeaker has built‑in protection to ensure that, in the event of a fire, damage to the loudspeaker does not result in failure of the circuit to which it is connected. In this way, system integrity is maintained; ensuring loudspeakers in other areas can still be used to inform people of the situation. The loudspeaker is supplied with a ceramic terminal block and thermal fuse.

Superb Sound Quality. The use of a high‑quality driver has resulted in a very natural sound reproduction with excellent bass response.
