C Series
The C-Series loudspeaker range from d&b audiotechnik has been optimized for flexible, modular array configurations and high sound pressure levels. Applications range from professional touring use and large-scale sound installations down to single cabinet set ups requiring narrow dispersion with minimum dimensions. The "d&b specific" combination of a neutral, intelligible sound character that is clear and transparent even at high sound pressure levels provides the engineer with an efficient, effortless tool and a neutral platform.

The C7-TOP is a coaxial, full range loudspeaker with a 75° x 40° constant directivity dispersion down to 600Hz. Its horn loaded 15” low frequency driver, 1.5” exit HF driver and an extended bass response allow use without a subwoofer wherever full range sound and controlled dispersion from a compact cabinet is required. The C7-SUB is a bass–reflex design with a large port and a long excursion 18” driver. It has the same footprint as the C7-TOP but is taller, allowing a frequency extension down to 44Hz and is ideal in a ground stack of two C7-SUBs and a C7-TOP. The C4 system is primarily for use in medium to large-scale sound reinforcement applications and allows the construction of scalable arrays with precise horizontal and vertical coverage. The C3, C4-TOP andC4-SUB have an identical cabinet shape, size and rigging, and along with the B2 subwoofer, form the basis of an arrayable, modular system. The C3 is a hornloaded line array module that can be arrayed both horizontally and vertically adding a long throw capability. The unique wave front adapter couples a total of three 1.3” exit drivers, which deliver a superbly controlled curved coherent wave front with vertical splay angles of 1° to 5° between the cabinets.

Ci Series
The d&b Ci-Series is a collection of loudspeaker systems and hardware fittings based on the established C series, specifically targeted for fixed installation use. The Ci-Series tackles the varied demands and requirements made on installed sound systems within the complete range of venue types and sizes. Accurate performance data for industry standard simulation software allows the installation designer to create solutions that are predictable and reliable for a wide range of applications, from the smallest to the largest venue.

Within the specific installation loudspeakers the Ci80 is a coaxial device that offers a symmetrical dispersion pattern in the horizontal and vertical planes while the cabinet may be mounted in either plane. The Ci45, Ci60 and Ci90 are identically sized cabinets whilst the Ci60 and Ci90 have physically symmetrical horn flanges enabling rotation of the horn assembly by 90° in the cabinets.
