The digitally stereable column speaker Ascolto AH2435 is particularly suitable to ensure an extended coverage in large environments, such as auditoriums, churches with long aisles, cathedrals, basilicas and in general where it needs simultaneously a very incisive beam and a bright tone, capable to transmit perfectly voice as well as music.
The multibeam DSP filtering technology steers the vertical radiation patterns, matching the desired listening pattern, making column speaker Ascolto AH2435 high directive and featuring the main propagation lobes less dependent on the frequency.
