2.1. Product description 2.1.1. 24c cardioid column loudspeaker the 24c is a passive 2-way column loudspeaker housing six 4” neodymium drivers and an hf array comprising six 1.1” dome tweeters. The 4" drivers are arranged in a unique cardioid setup radiating through waveguide elements at the front a...

2.1.3. Cardioid dispersion due to their dimensions, conventional column loudspeakers provide no significant horizontal directivity below 2 khz. At low and mid frequencies, the resulting polar pattern is almost omni-directional (dotted line). The cardioid patterns of the 24c and 24c-e show a much hig...

2.1.6. Aiming of the beam the aiming of the beam of the hf array can be adjusted between 0° and –14°. The dmax/h scale on the left provides a simple means of determining the correct setting for a given room geometry. The assumption here is the listening plane is horizontal and the loudspeaker column...
