Product description

The 24C-E passive extender is for use with the 24C column loudspeaker. The cabinet houses six 4” neodymium drivers, providing an extension of vertical directivity down by a further octave to 190 Hz. Connections between the loudspeakers are made passively, requiring only one amplifier channel. The 4" drivers are arranged in a unique cardioid setup utilizing damped ports at the rear of the cabinet. This design provides a broadband attenuation to the rear of approximately 18 dB. The 24C-E 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 24C-E features extendable rails to accommodate the attachments of the 24C. N-lok connectors are incorporated within the cabinet to link with the 24C loudspeaker. 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 d&b 10D, 30D and D6 amplifiers are recommended to drive the 24C-E. The d&b D20 and D80 can also be used. The 24C-E column extension is powered directly from the 24C loudspeaker.
