Harmonic Design introduces the hd IC170 ceiling loudspeaker

With the hd IC170 Harmonic Design is expanding its portfolio in the installation area with a compact ceiling loudspeaker. The specialty lies in the extraordinary sound compatibility with the coaxial column loudspeakers of the hd CCX-Series. This is made possible by the use of the tried and tested 3.5″ woofer chassis with a coaxially arranged 1″ tweeter and its linear transmission behavior with excellent speech intelligibility. This means that applications such as in conference rooms with main sound system from hd C7CX column speakers and delay / side rooms with hd IC170 ceiling speakers can be equipped with the least amount of processing and setup effort, and the same sound can be achieved.

New product: hd PC150 pendant speaker

Harmonic Design Pendulum Ceiling loudspeakers are ideally suited for rooms with high ceilings and sophisticated architecture. The minimalist design with a clear shape as a cylinder and resemblance to hanging lamps is suitable for decentralized and large-area sound reinforcement tasks such as in shopping centers, showrooms, hotels, restaurants or airports.

The elegant and durable aluminum housing with bass reflex tuning allows full-fledged music playback despite the most compact dimensions and can be customized in terms of color, surface and pattern. The hd PC150 is also based on the innovative dual-concentric loudspeaker chassis from the hd CCX-Series and, thanks to the detachable bracket, can be attached using a suitable combination cable incl. wire rope, it is child’s play to hang from ceilings of variable heights.
