Product Overview

16C 2-Way Passive Column Loudspeaker

The 16C 2-way passive column loudspeaker is the smallest in the Series housing four 4” neodymium drivers and a 0.75” compression driver mounted on a CD horn. The HF horn has a nominal dispersion of 90° x 40° (h x v). 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 16C 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 16C column loudspeaker will be available in the 2nd quarter of 2014.

Features

 

Cardioid dispersion

Conventional column loudspeakers provide no significant horizontal directivity below 2 kHz due to their physical size. At low and mid frequencies, the resulting polar pattern is almost omni-directional as shown by the dotted line in the Free field horizontal polar plot illustration. The continuous line shows the cardioid pattern of the 24C/24C-E with reduced radiation to the rear of the loudspeaker.

Free field horizontal polar plot, conventional vs cardioid column loudspeaker

Typically, column loudspeakers are mounted onto walls or other hard plane surfaces which act as an acoustic mirror, as shown in the Wall mounted horizontal polar plot illustration. This results in the room not only being covered by the sound of the actual column loudspeaker, but also by the sound produced by its virtual mirror source from behind. In the case of conventional column loudspeakers, the mirror source radiates at a similar level as the loudspeaker itself. The combination of both sources results in a dipolar characteristic where the main energy is radiated along the walls as indicated by the dotted line. With their cardioid dispersion patterns, when similarly wall mounted, the 24C/24C-E provide an even dispersion characteristic and useful directivity, as shown by the continuous line in the Wall mounted horizontal polar plot.
