About the d & b Audiotechnik C7 series
The d & b Audiotechnik C7 Series comprises two complementary cabinets. The C7-TOP is a 2-way horn-loaded loudspeaker featuring a 15-inch driver and a 1.5-inch compression driver, with a bass-reflex low-end design that maintains true constant directivity above 600 Hz. This allows the C7-TOP to operate without a subwoofer and makes it well suited to balcony or stadium sound reinforcement, delay lines and background music playback. The C7-SUB is an 18-inch bass-reflex subwoofer designed specifically for use alongside the C7-TOP, with an extra-large bass-reflex tunnel engineered to deliver high sound pressure levels while minimising power compression and air turbulence noise. Up to two C7-SUBs can be stacked with a single C7-TOP.
d & b Audiotechnik C7 series — buyer FAQs
What is the d & b Audiotechnik C7 Series and what does it consist of?
The d & b Audiotechnik C7 Series is a professional loudspeaker system made up of two complementary cabinets: the C7-TOP full-range loudspeaker and the C7-SUB bass-reflex subwoofer. The C7-TOP is a 2-way horn-loaded design with a 15-inch driver and a 1.5-inch compression driver, while the C7-SUB uses an 18-inch driver in a bass-reflex enclosure built specifically to work alongside it.
What applications is the C7-TOP suited to, and can it be used without a subwoofer?
The C7-TOP is suited to balcony and stadium sound reinforcement, delay lines and background music playback. Its bass-reflex low-end design means it can operate without a subwoofer where extended bass is not required. When deeper low-frequency output is needed, up to two C7-SUBs can be stacked with a single C7-TOP.
What makes the C7-TOP's directivity performance notable?
The C7-TOP maintains true constant directivity above 600 Hz, which is a result of its horn-loaded 2-way configuration. This makes coverage predictable and consistent across its operating range, a practical advantage in venues such as stadiums or balcony configurations where controlled dispersion and extended throw matter.
Who makes the C7 Series and where does it sit in their range?
The C7 Series is made by d & b Audiotechnik, a German professional audio manufacturer founded in 1981 and based in Backnang, Germany. The company produces loudspeaker systems, line arrays, subwoofers, amplifiers and system control software for the rental, touring and installation markets, with all products manufactured in Germany. The C7 Series addresses stadium, balcony and delay reinforcement requirements within that portfolio.
What should I check when buying a used d & b Audiotechnik C7 Series cabinet?
Check whether the unit is the C7-TOP, the C7-SUB, or both, since pricing and usefulness depend on the configuration. Inspect driver condition on the C7-TOP (15-inch low-frequency driver and 1.5-inch compression driver) and the 18-inch driver and bass-reflex tunnel on the C7-SUB.
