The hd C4
is a passive 1-way miniature speaker, equipped with four 2″ broadband drivers with linear frequency response. The operation can be done via any power amplifier without DSP and makes the hd C4 the optimal solution for decentralized or small sound applications such as restaurants, conference rooms or theaters. The hd C4 can be flexibly and easily fixed or can be used on a mobile basis. Using the discreet ball joint wall mount, the hd C4 can be easily swiveled and tilted or mounted with the L-angle wall mount extremely close and unobtrusive to the surface to be fixed. Internal terminal block connections ensure a tool-free and quick connection of the loudspeakers. For optimum adaptation to the room architecture, the loudspeaker can be customized in all RAL colors and special lengths. If wall mounting is not possible, the speakers can be used with the optional 3/8″ threaded base plate and SpeakCON jack on a microphone stand.
Extremely powerful subwoofers of the hd Sub- or hd P-Series with up to 1800 W AES power handling capacity extend the low-frequency sound experience down to the infrasound range. The most elegant solution for extending the bass range of the hd C-Series is the super slim hd Slim265 design subwoofer. Due to its low height of just 102 mm, it fits into any suspended ceiling, can be mounted on a wall or placed invisibly under a piece of furniture.
Applications in existing or newly developed distributed systems can be realized with the optional 100V versions. Modern transformers guarantee high audio performance even over long distances and with small cable cross-sections. Several power taps make it possible to adjust the sound level.
