About the d & b Audiotechnik C3
The d & b Audiotechnik C3 is a 2-way active hornloaded line array module built for use within the d & b C4 system. Each cabinet houses two 10-inch drivers and three 1.3-inch compression drivers, delivering a horizontal dispersion of 35 degrees above 900 Hz and a 5-degree vertical HF dispersion. Multiple units stack into vertical columns that produce a curved coherent wavefront, providing sufficient mid and high frequencies at distant listening positions. The C3 is fully compatible with C4 loudspeakers, sharing an identical cabinet shape and rigging accessories. Cabinet construction uses marine plywood with an impact-resistant paint finish, steel handles, MAN CF4 stud plate rigging points, ratchet strap guide plates, hinge plates and heavy-duty wheels.
d & b Audiotechnik C3 — buyer FAQs
What is the d & b Audiotechnik C3 and what role does it play in a line array system?
The d & b Audiotechnik C3 is a 2-way active hornloaded line array module designed to work within the d & b C4 system. Multiple C3 cabinets stack into vertical columns that produce a curved coherent wavefront, with the module's role being to deliver mid and high frequencies to distant listening positions rather than covering low-frequency content.
What are the dispersion characteristics of the C3?
The C3 provides a horizontal dispersion of 35 degrees above 900 Hz and a 5-degree vertical HF dispersion per cabinet. The narrow vertical dispersion is intentional: when multiple units are combined into a vertical column, each cabinet contributes to a curved coherent wavefront that maintains consistent coverage across long throw distances.
How is the C3 cabinet built, and what rigging hardware does it include?
The C3 cabinet is constructed from marine plywood with an impact-resistant paint finish. It includes steel handles, MAN CF4 stud plate rigging points, ratchet strap guide plates, hinge plates and four heavy-duty wheels. Fittings at the top and bottom accept an optional wooden lid, making the cabinet practical for touring and installation environments.
Is the d & b Audiotechnik C3 compatible with other cabinets in the C4 system?
Yes. The C3 is fully compatible with d & b C4 loudspeakers because it shares an identical cabinet shape and the same rigging accessories. This means C3 and C4 units can be integrated into the same vertical array without needing separate rigging hardware or adapters.
Who makes the C3, and where does it sit in their product range?
The C3 is made by d & b audiotechnik, a German professional audio manufacturer based in Backnang, Germany. The company produces loudspeaker systems, line arrays, subwoofers and amplifiers for rental, touring and installation markets, and the C3 sits within the C-series as a companion mid-high module built specifically to complement the C4 loudspeaker system.
