The 2-way passive xC-Series column loudspeakers are elegantly engineered to provide effective, discreet solutions for acoustically challenging environments. The streamline 16C, 24C and 24C-E all incorporate 4“ drivers in a special design radiating through waveguide elements at the front and damped ports at the rear of the cabinet. The resulting cardioid dispersion pattern, along with a nominal dispersion angle of no more than 90° minimizes side emissions caused by wall reflections in the low and mid frequencies, eliminating cancellations and reducing the stimulation of the reverberant field, and increasing gain before feedback. Furthermore, the 24C loudspeaker achieves remarkable vertical directivity control down to 370 Hz, which is increased by a complete octave when attached to the dedicated 24C-E column extender. The 24C features a HF array with a nominal 20° vertical dispersion, which is mechanically adjustable from 0° to -14° to exactly target the audience listening area. All xC cabinets are fitted with two continuous rails at the rear, enabling the loudspeakers to be fitted as close and parallel to the wall as possible. With the xC-Series available in black or white as standard or specially colour matched to interiors, the d&b columns guarantee maximum intelligibility with minimal visual disturbance.
