The new ALM series transmits clear intelligible live announcements and precise messages. Thanks to the digitally controllable directional effect, the entire frequency spectrum can be heard in the desired sound coverage area. The combination of a long range and a wide horizontal opening angle has the advantage that just a few ALM loudspeakers cover a large area. Therefore, the ALM loudspeakers are particularly suitable for installations where a high level of speech intelligibility is required, for example in lecture halls, places of worship, airport terminals or shopping center.
