d&b audiotechnik 24C column

The 24C 2-way passive column loudspeaker features six 4” neodymium drivers and a HF array comprising six 1.1” dome tweeters providing a nominal horizontal dispersion of 90°. The HF array has a nominal vertical dispersion of 20°, which can be adjusted constantly between 0° and -14° to target audience listening areas. The beam produced by the low / mid drivers is tilted downwards by 5°, offering significant directivity down to 370 Hz. The 4″ drivers are arranged in a unique cardioid setup radiating through waveguide elements at the front and damped ports at the rear of the cabinet. This design provides a constant directivity pattern of 90° in the horizontal plane with a broadband attenuation to the rear of approximately 18 dB. A cardioid dispersion pattern produces minimal energy behind the loudspeaker, reducing reflections and resulting in balanced level distribution across the listening area while increasing gain before feedback when working with open microphones. The 24C loudspeaker enclosure is constructed from an extruded aluminium back and a metal baffle, while the front and sides of the cabinet are protected by a metal grill. The rear of the cabinet features continuous T-slot rails for mounting purposes and a 4-pole Phoenix combicon terminal connector. The xC-Series loudspeakers are available in white or black as standard, or can be provided with the Special Colour (SC) option that can be executed in all RAL colours.

The 24C can be combined with the 24C-E passive extension increasing vertical pattern control down to 190 Hz.
